Associations between chronotype,sleep disturbances and seasonality with fatigue and inflammatory bowel disease symptoms

Growing number of studies suggests link between circadian rhythms and inflammatory bowel diseases (IBD) manifestation. We hypothesize that: 1) IBD are associated with increased eveningness and sleep disturbances; 2) eveningness and sleep disturbances are related to more severe IBD symptoms. In total, 129 participants were enrolled to this study, divided into three groups: 34 Crohn’s disease (CD) patients, 38 ulcerative colitis (UC) patients and 57 healthy controls (HC) group. They all fulfilled a questionnaire, consisting of the Composite Scale of Morningness (CSM), Seasonal Pattern Assessment Questionnaire (SPAQ), Pittsburgh Sleep Quality Index, Inflammatory Bowel Disease Questionnaire (IBDQ) and Multidimensional Fatigue Inventory (MFI). Multiple regression models controlled for age and sex revealed that in CD group higher eveningness measured with CSM was associated with higher general fatigue, physical fatigue, mental fatigue and reduced motivation measured by MFI. Lower CSM morning affect is associated with greater general fatigue, physical fatigue and more reduced activity. Greater seasonality scores are associated with increased physical fatigue and more reduced activity and motivation. Lower sleep quality measured with PSQI is associated with higher physical fatigue and more reduced activity. Correlational analysis revealed that higher seasonality and lower sleep quality are associated with increased systemic and bowel symptoms and decreased emotional and social functions measured with IBDQ. In UC group, eveningness is associated with greater general fatigue, physical fatigue and more reduced activity. Higher CSM morning affect is associated with decreased general fatigue, physical fatigue and less reduced activity. Higher CSM circadian preference scores are associated with decreased general and physical fatigue, and less reduced activity. Increased seasonality is associated with more physical fatigue. Lower sleep quality is associated with greater general and physical fatigue. To our best knowledge this is the first study evaluating associations between chronotype and sleep disturbances with IBD symptoms. We have found that chronotype preferences, whose role in IBD has been until now overlooked, may be one of the important factors contributing to fatigue in this clinical group.     

Population based study of fatigue and psychological distress.

OBJECTIVES--To determine the prevalence of fatigue in the general population and the factors associated with fatigue. DESIGN--Postal survey. SETTING--Six general practices in southern England. SUBJECTS--31,651 men and women aged 18-45 years registered with the practices. MAIN OUTCOME MEASURES--Responses to the 12 item general health questionnaire and a fatigue questionnaire which included self reported measures of duration, severity, and causes of fatigue. RESULTS--15,283 valid questionnaires were returned, giving a response rate of 48.3%, (64% after adjustment for inaccuracies in the practice registers). 2798 (18.3%) of respondents reported substantial fatigue lasting six months or longer. Fatigue and psychological morbidity were moderately correlated (r = 0.62). Women were more likely to complain of fatigue than men, even after adjustment for psychological distress. The commonest cited reasons for fatigue were psychosocial (40% of patients). Of 2798 patients with excessive tiredness, only 38 (1.4%) attributed this to the chronic fatigue syndrome. CONCLUSION--Fatigue is distributed as a continuous variable in the community and is closely associated with psychological morbidity.     

Association of Common Mental Disorders and Quality of Life with the Frequency of Attendance in Slovenian Family Medicine Practices: Longitudinal Study

Background

Most research on frequent attendance has been cross-sectional and restricted to one year attendance rates. A few longitudinal studies suggest that frequent attendance is self-limiting. Frequent attenders are more likely to have social and psychiatric problems, medically unexplained physical symptoms, chronic somatic diseases (especially diabetes) and are prescribed more psychotropic medication and analgesics.

Research Question

To describe the attendance rates in a longitudinal study and to test if depression, panic syndrome, other anxiety syndrome, alcohol misuse and general quality of life are associated with frequent attendance in next two consecutive years.

Methods

1118 consecutive family practice attendees, aged 18 to 75 years from randomly selected family medicine practices were recruited at baseline and followed up at 12 and 24 months. We identified frequent attenders in the top 10 centile within one year. Using a multivariate model, we ascertained if presence of common mental disorders and quality of life assessed at baseline in 2003 predict frequent attendance in 2004 and 2005.

Results

40% of frequent attenders continue to be frequent attenders in the following year and 20% of the frequent attenders were so for the 24 month period. Lower physical scores on the SF-12 questionnaire were strongly associated with future frequent attendance at 12 and 24 months. There was a trend for people with greater than elementary school education to be less likely to become frequent attenders at both 12 and 24 months. For other variables these effects were less consistent. Presence of major depression, panic syndrome, other anxiety syndrome and alcohol misuse were not predictive of frequent attendance in the following two years.

Conclusion

Low physical quality of life is strongly predictive of higher frequent attendance and similar finding was observed for people with lower educational level but further confirmatory research is required to establish this association.     

Effect of non-attenders on the potential of a primary care programme to reduce cardiovascular risk in the population. Family Heart Study Group.

OBJECTIVES--To determine the feasibility of enrolling non-attenders of a population based cardiovascular risk reduction programme (the British family heart study) into a further, similar programme and to assess the effect of non-attendance on the effectiveness of the programme. DESIGN--Follow up of non-attenders by practice nurses, including home visits if necessary, to administer questionnaires and obtain physiological measurements. SETTING--Eight general practices across England, Scotland, and Wales. SUBJECTS--Non-attenders in a cardiovascular risk factor screening and intervention programme compared with attenders. MAIN OUTCOME MEASURES--Number of non-attenders enrolled; sociodemographic characteristics; personal and family history of coronary heart disease; cardiovascular risk factors; and total coronary risk score. RESULTS--Data were collected from 106 (17%) of the 608 non-attending families (99 men and 42 women). Of the 543 non-attending families from five practices that attempted complete follow up, 256 had moved away or died. Only 76 were eventually enrolled into the study. The prevalence of coronary heart disease and a family history of coronary heart disease were similar among non-attenders and attenders as were the individual coronary risk factors studied except smoking. Women non-attenders were more likely to be current cigarette smokers than attenders (15/42 v 202/948, P = 0.02). CONCLUSIONS--The intensive follow up of non-attenders resulted in real intervention opportunities in only a small number. Since the effect of any intervention in a population is reduced by non-attendance audit of preventive medical programmes aimed at the population should allow for the effect of non-attenders on the overall results.     

Career preferences of doctors who qualified in the United Kingdom in 1993 compared with those of doctors qualifying in 1974, 1977, 1980, and 1983.

OBJECTIVE--To report the career preferences of doctors who qualified in the United Kingdom in 1993 and to compare their choices with those of earlier cohorts of qualifiers. DESIGN--Postal questionnaires with structured questions, including questions about choice of future long term career, were sent to doctors a year after qualification. SETTING--United Kingdom. SUBJECTS--All medical qualifiers of 1993, comparing their replies with those from earlier studies of the qualifiers of 1974, 1977, 1980, and 1983. MAIN OUTCOME MEASURES--Choice of future long term career and certainty of choice expressed at the end of the first year after qualification. RESULTS--Questionnaires were sent to 3657 doctors. 2621 (71.7%) replied. Of the 2621 respondents, 70.5% (1849) stated that their first preference was for a career in hospital practice, 25.8% (677) specified general practice, 1.0% (25) specified public health medicine or community health, 1.4% (36) specified careers outside medicine, and 1.3% (34) did not state a choice. By contrast, 44.7% (1416/3168) of the doctors in the 1983 cohort had specified that their first preference was general practice. Among the 1993 qualifiers, general practice was the first career choice of 17.5% of men (227/1297) and 34.0% of women (450/1324). Only 7.4% of men (96/1297) stated that they definitely wanted to enter general practice. Only 7.8% (103/1324) of women qualifiers in 1993 expressed a career preference for surgical specialties. Within hospital practice, comparing 1993 with 1983, choices for the medical specialties and for accident and emergency medicine rose and those for pathology fell. Women were less definite than men about their choice of future long term career. CONCLUSIONS--If the 1993 cohort is typical of the current generation of young doctors, there has been a substantial shift away from general practice as a career choice expressed at the end of the preregistration year. General practice was much more popular among women than men. Few women opted for surgery. The sex imbalance in the percentage of doctors who choose different mainstreams of medical practice seems set to continue.     

Androgen deficiency in male patients diagnosed with ANCA-associated vasculitis: a cause of fatigue and reduced health-related quality of life?

Introduction

Low testosterone levels in men are associated with fatigue, limited physical performance and reduced health-related quality of life (HRQOL); however, this relationship has never been assessed in patients with anti-neutrophil cytoplasmic antibodies (ANCA) -associated vasculitides (AAV). The aim of this study was to assess the prevalence of androgen deficiency and to investigate the role of testosterone in fatigue, limited physical condition and reduced HRQOL in men with AAV.

Methods

Male patients with AAV in remission were included in this study. Fatigue and HRQOL were assessed by the multi-dimensional fatigue inventory (MFI)-20 and RAND-36 questionnaires.

Results

Seventy male patients with a mean age of 59 years (SD 12) were included. Scores of almost all subscales of both questionnaires were significantly worse in patients compared to controls. Mean total testosterone and free testosterone levels were 13.8 nmol/L (SD 5.6) and 256 pmol/L (SD 102), respectively. Androgen deficiency (defined according to Endocrine Society Clinical Practice Guidelines) was present in 47% of patients. Scores in the subscales of general health perception, physical functioning and reduced activity were significantly worse in patients with androgen deficiency compared to patients with normal androgen levels. Testosterone and age were predictors for the RAND-36 physical component summary in multiple linear regression analysis. Testosterone, age, vasculitis damage index (VDI) and C-reactive protein (CRP) were associated with the MFI-20 subscale of general fatigue.

Conclusions

This study showed that androgen deficiency was present in a substantial number of patients with AAV. Testosterone was one of the predictors for physical functioning and fatigue. Testosterone may play a role in fatigue, reduced physical performance and HRQOL in male patients with AAV.     

Skeletal muscle fatigue, strength, and quality in the elderly: the Health ABC Study.

We examined the muscle fatigue characteristics in older men and women and determined whether these were related to the size, strength, or quality of muscle. A total of 1,512 men and women aged 70-79 yr from the Health, Aging, and Body Composition Study participated in this study. Muscle cross-sectional area and attenuation were determined with computed tomography. Skeletal muscle fatigue and strength (peak torque) of the knee extensors and flexors were measured using isokinetic dynamometry. Men were more fatigue resistant than women for both knee extension (fatigue index: 70.4 +/- 15.3 vs. 66.9 +/- 14.3%; P < 0.05) and knee flexion (67.9 +/- 16.4 vs. 64.9 +/- 17.6%; P < 0.05). Peak torque and muscle quality (specific torque) were higher in men than women for knee extension (99.6 +/- 28.2 vs. 63.0 +/- 16.8 N x m and 1.62 +/- 0.43 vs. 1.51 +/- 0.39 N x m/cm2; both P < 0.05) and for knee flexion (74.0 +/- 26.4 vs. 49.6 +/- 15.9 N x m and 2.47 +/- 1.29 vs. 2.22 +/- 0.78 N x m/cm2; both P < 0.05). Total work and power output was greater in men compared with women for both the quadriceps (1,353 +/- 451 vs. 832 +/- 264 J and 87.7 +/- 33.5 vs. 53.3 +/- 19.2 W; both P < 0.05) and the hamstrings (741 +/- 244 vs. 510 +/- 141 J and 35.4 +/- 16.0 vs. 23.7 +/- 10.2 W; both P < 0.05). In both genders, the quadriceps was able to perform more work with greater power compared with the hamstrings. Those who were stronger actually had greater fatigue after adjusting for age, race, physical activity, and total body fat. In conclusion, older men were more fatigue resistant than women, although in both men and women greater fatigue was not related to muscle weakness.     

Human immunodeficiency viruses in patients attending a sexually transmitted disease clinic in London, 1982-7.

OBJECTIVE--To determine the prevalence of infection with the human immunodeficiency virus (HIV) in all patients attending a London sexually transmitted disease clinic over four weeks at the end of 1987 and to see how it varied from that in similar samples studied between 1982 and 1986. DESIGN--Anonymous testing of serum samples from consecutive heterosexual and homosexual patients having routine serological investigations for syphilis. Testing was for anti-HIV-I, anti-HIV-II, and hepatitis B core antibody (anti-HBc) and P24 antigen. Age, nationality, sexual orientation, and past sexually transmitted diseases were recorded for each patient. Gonorrhoea rates by quarters were analysed among homosexual and bisexual men and heterosexual men and women from 1981 to 1987. SETTING--Outpatient department of genitourinary medicine. PATIENTS--A total of 1074 patients attending consecutively for syphilis serology. Thirty five homosexual and bisexual men were excluded (these were regular attenders as part of a prospective study of the natural course of HIV infection). MEASUREMENTS AND MAIN RESULTS--The prevalence of anti-HIV-I in homosexual and bisexual men in 1987 was 25.6% (64/250). Results in the same clinic population between 1982 and 1984 had shown a rise in prevalence, which flattened out in 1985-6 and continued at that level. Among heterosexual attenders in 1987 the prevalence of anti-HIV-I was 1% (women 4/412; men 4/377), which contrasted with a prevalence of 0.5% (women 2/395; men 3/757) in January 1986. One homosexual man was seropositive for anti-HIV-II and seronegative for anti-HIV-I. Among homosexual and bisexual men the rate of gonorrhoea had declined by an average of 2.7% a year since 1981, such that by 1987--and for the first time in the clinic--there was no significant difference in the rates between these men and heterosexual men and women. CONCLUSIONS--The appearance of HIV-I infection among heterosexuals indicates a need for more aggressive education programmes and intervention strategies along the lines adopted for homosexual men. Surveillance for HIV-II infection is needed to provide information for future policy in national screening programmes.     

Prevalence of coronary heart disease risk factors in a Cambridge, UK study

This paper examines the distribution and prevalence of risk factors for coronary heart disease in a sample of 165 men and 202 women over 40 years of age who had earlier participated in a coronary prevention trial from a general practice in Cambridge, UK. No significant differences were observed in total cholesterol levels between men and women, and a quarter of the sample had concentrations above 6.5 mmol/l which is 250 mg/dl. There were significant sex differences in a number of risk factors with males having significantly higher prevalence of low high density lipoprotein, systolic and diastolic blood pressures, obesity, and smoking than women. About 8% of men and women were obese (as defined by a body mass index > 30), while 47% of men and 35% of women were mildly overweight (body mass index > 25). Two or more risk factors for coronary heart disease (high total cholesterol and/or hypertension and/or obesity) were present in 4% and 9% of older men and women respectively. Furthermore, about half the subjects had more than one risk factor for coronary heart disease.     

Sleep Disordered Breathing,Fatigue, and Sleepiness in HIV-Infected and -Uninfected Men

Study Objectives

We investigated the association of HIV infection and highly active antiretroviral therapy (HAART) with sleep disordered breathing (SDB), fatigue, and sleepiness.

Methods

HIV-uninfected men (HIV−; n = 60), HIV-infected men using HAART (HIV+/HAART+; n = 58), and HIV-infected men not using HAART (HIV+/HAART−; n = 41) recruited from two sites of the Multicenter AIDS cohort study (MACS) underwent a nocturnal sleep study, anthropometric assessment, and questionnaires for fatigue and the Epworth Sleepiness Scale. The prevalence of SDB in HIV- men was compared to that in men matched from the Sleep Heart Health Study (SHHS).

Results

The prevalence of SDB was unexpectedly high in all groups: 86.7% for HIV−, 70.7% for HIV+/HAART+, and 73.2% for HIV+/HAART−, despite lower body-mass indices (BMI) in HIV+ groups. The higher prevalence in the HIV− men was significant in univariate analyses but not after adjustment for BMI and other variables. SDB was significantly more common in HIV− men in this study than those in SHHS, and was common in participants with BMIs <25 kg/m². HIV+ men reported fatigue more frequently than HIV− men (25.5% vs. 6.7%; p = 0.003), but self-reported sleepiness did not differ among the three groups. Sleepiness, but not fatigue, was significantly associated with SDB.

Conclusions

SDB was highly prevalent in HIV− and HIV+ men, despite a normal or slightly elevated BMI. The high rate of SDB in men who have sex with men deserves further investigation. Sleepiness, but not fatigue, was related to the presence of SDB. Clinicians caring for HIV-infected patients should distinguish between fatigue and sleepiness when considering those at risk for SDB, especially in non-obese men.     

Urinary incontinence: prevalence,need for treatment,and effectiveness of intervention by nurse.

OBJECTIVE--To measure the unmet need of patients with regular urinary incontinence (incontinence twice or more a month) treatable by a nurse. DESIGN--Self completed postal questionnaire and randomised controlled trial of assessment and intervention by a nurse. SETTING--One urban and one rural general practice in Somerset. SUBJECTS--7300 adults randomly selected from 10,300 aged 35 and over on the combined practice lists. 515 women and 185 men with regular incontinence were offered assessment and treatment, of whom 134 women and 49 men had no intervention for three months (historical controls). They then joined the assessment and treatment programme. INTERVENTION--Four sessions of pelvic floor exercises and bladder retraining supervised by non-specialist nurse who had taken a three week course on assessing and treating uncomplicated incontinence. MAIN OUTCOME MEASURES--Number of patients desiring treatment; self reported cure, improvement, or deterioration in continence after three months. RESULTS--The questionnaire achieved a 79% response. Validated responses showed a prevalence of 4.4% in men and 16.4% in women aged 35-64. 315 (45%) of the 700 patients offered assessment refused it and seven had moved away or died, 64 men and 41 women were referred to their general practitioner. 197 of 292 treated women (68%) reported cure or improvement compared with seven (5%) of controls. 22 of the 86 men desiring treatment were suitable for intervention by the nurse. Seventeen were cured or improved compared with none of the men in the control group. CONCLUSIONS--About half the people with regular urinary incontinence took up the offer of treatment (9.2% of women and 3.4% of men in the study population). This condition can be effectively managed by a nurse with limited training.     

Recruitment,retention, and time commitment change of general practitioners in England and Wales, 1990-4: a retrospective study.

OBJECTIVES: To describe the recruitment and retention of general practitioners and changes in their time commitment from 1 October 1990 to 1 October 1994. DESIGN: Retrospective analysis of yearly data. SETTING: England and Wales. SUBJECTS: General practitioners in unrestricted practice. MAIN OUTCOME MEASURES: Numbers of general practitioners moving into and out of general practice; proportion of general practitioners practising less than full time; proportion of general practitioners having unchanged time commitment over the study period; and proportion of general practitioners leaving general practice in 1991 who were subsequently practising in 1994. RESULTS: Numbers of general practitioners entering general practice (1565 in 1990, 1400 in 1994) fell over the study period as did the numbers leaving general practice (1488 in 1990, 1115 in 1994). The net effect was an increase in both the total and full time equivalent general practitioners practising from 1 October 1990 (26,757 full time equivalents) to 1 October 1994 (27,063 full time equivalents). Numbers of general practitioners practising full time were decreasing whereas part time practice was increasing; women were more likely to practise part time. 35.5% (43/121) of women practising full time and 17.8% (24/135) of men practising full time who left practice in 1991 were practising again in 1994. CONCLUSION: Simply using total numbers of general practitioners or net increase to describe workforce trends masks much movement in and out of general practice and between differing time commitments. Recruitment and retention issues need to be separated if reasonable policies are to be developed to assure the necessary general practitioner workforce for a primary care led NHS.     

Employment experiences of vocationally trained doctors.

OBJECTIVES--To investigate the expectations and employment experiences of male and female doctors who completed vocational training in East Anglia during 1981-7 and to examine the factors which had influenced those who had changed direction early in their careers. DESIGN--Survey conducted by confidential postal questionnaire. SETTING--Britain. SUBJECTS--281 doctors, 233 (83%) of whom responded. MAIN OUTCOME MEASURES--Ideal choice of work on completion of vocational training; present employment; factors which had restricted present choice of work; factors associated with reported satisfaction with job. RESULTS--77/83 (93%) men and 130/150 (87%) women had hoped to work in general practice (p = 0.75). A smaller proportion of women (71%; 106) than men (89%; 74) were in general practice posts (p less than 0.01); only 6% (nine) of women were on maternity leave or caring for children without paid employment. More women than men were working in medical jobs other than general practice (18% (27) women v 4% (three) men; p less than 0.01). 44/91 (49%) women with children had achieved their employment goals compared with 47/59 (80%) women without children and 55/71 (78%) men with children. 87% (72/83) of men and 65% (98/150) of women had achieved the status of principal (p less than 0.01). 162/193 (84%) doctors who had worked in general practice reported satisfaction with their jobs. Dissatisfaction was linked with doing a job different from that hoped for and with perceiving that the share of practice income did not accurately reflect their share of the practice workload. CONCLUSIONS--Steps need to be taken to retain women in general practice, including a statutory part time pay allowance and incentives for practices to allow flexible working hours for doctors with young children.     

Mercury toxicity presenting as chronic fatigue, memory impairment and depression: diagnosis, treatment, susceptibility, and outcomes in a New Zealand general practice setting (1994-2006)

In a group of 465 patients diagnosed as having chronic mercury toxicity (CMT), 32.3% had severe fatigue, 88.8% had memory loss, and 27.5% had depression. A significant correlation was found between CMT and the Apo-lipoprotein E4 genotype (p=0.001). An investigation into an additional 864 consecutively seen general practice patients, resulted in 30.3% having evidence consistent with CMT, and once again a significant correlation was found with the APO-E4 genotype (p=0.001). Removal of amalgam mercury fillings when combined with appropriate treatment resulted in a significant symptom reduction (p<0.001) to levels reported by healthy subjects.     

Age,pattern of consultation,and functional disability in elderly patients in one general practice.

OBJECTIVE--To examine how functional disability varies with sex, age, and other variables in patients aged 75 and over living in the community and to ascertain whether a statistical model derived from the variables in this population usefully predicted functional disability in another of similar age. DESIGN--Retrospective study of data collected by interview and by examination of medical records. SETTING--An urban general practice with five partners and a list of 15,000 patients, very few of whom belonged to ethnic minorities. PATIENTS--775 Patients (252 men, 523 women) aged 75 and over living in the community between September 1985 and August 1986; 13 other patients considered to be unsuitable and 14 who declined an interview were excluded. Also 94 patients who became 75 or joined the practice after August 1986. MAIN OUTCOME MEASURE--The proportions of fit, partially disabled, and severely disabled (housebound) patients. RESULTS--90 Men (35.7%) and 128 women (24.5%) were fit, and 27 men (10.7%) and 116 women (22.2%) were housebound; in all age groups women were significantly more likely to be disabled than men. A significant trend towards greater disability was shown with increasing age and, more noticeably, with pattern of consultation when patients were divided into three categories based on the number of times they had attended the surgery and been visited at home over about two years. Statistical models gave the forecast percentage of fit and severely disabled patients for each sex, age group, and pattern of consultation, and a simple scheme was derived to identify from information wholly contained in medical records most of those patients most prone to severe disability. The scheme was verified applying it to a population of 94 elderly patients in 1988-9. CONCLUSION--Sex, age, and pattern of consultation together provide a quick indication of elderly patients'' tendency to severe disability, which can help in screening and in day to day consultations.     

The Chronic Fatigue Twin Registry: method of construction, composition, and zygosity assignment.

Chronic fatigue syndrome (CFS) and the symptom of chronic fatigue are conditions of unknown etiology. The Centers for Disease Control and Prevention (CDC) define CFS as an illness characterized by > or = 6 months of disabling fatigue associated with muscle pain, pharyngitis, and alterations in mood, sleep and neurocognition. We constructed a registry of twins with chronic fatigue to facilitate research on the impact of illness, the associated medical and psychosocial factors, and the heterogeneous proposed mechanisms for these conditions. We have recruited 204 twin pairs in which one or both members reported persistent fatigue through patient support group newsletters (60%), clinicians/researchers familiar with CFS (12%), notices placed on electronic bulletin boards for CFS (11%), twin organizations and researchers (6%), relatives and friends (3%) and other sources (8%). Complete data are available for 177 pairs (87%). Twins completed an extensive questionnaire booklet that included measures of physical and mental health, functional status, and psychosocial factors; a structured psychiatric interview was also conducted by telephone. Twins were classified using three increasingly more stringent diagnostic criteria for chronic fatigue: 1) > or = 6 months of fatigue (115 discordant and 61 concordant pairs); 2) chronic fatigue with additional symptoms and application of the medial exclusions of the CDC CFS case definition as obtained by self-report (92 discordant and 41 concordant pairs) and; 3) chronic fatigue with additional symptoms unexplained by self-reported medical conditions and psychiatric diagnoses as determined by the structured interview (69 discordant pairs and 25 concordant pairs). Despite the limitations of a volunteer registry, the Chronic Fatigue Twin Registry promises to be an important resource for research on CFS and chronic fatigue.     

Prevalence of Overweight and Obesity and Weight Loss Practice among Beijing Adults, 2011

Objective

This study aims to determine the up-to-date prevalence of overweight and obesity, the distributions of body weight perception and weight loss practice in Beijing adults.

Methods

A cross-sectional study was conducted in 2011. A total of 2563 men and 4088 women aged 18–79 years from the general population were included. Data were obtained from questionnaire and physical examination.

Results

The prevalence of overweight (BMI 24–27.9 kg/m²) and obesity (BMI≥28 kg/m²) was 42.1% and 20.3% in men and 35.6% and 17.1% in women, respectively. Age was inversely associated with overweight in both sexes, and obesity in women. Education level was negatively associated with overweight and obesity in women but not in men. Only 49.1% men and 58.3% women had a correct perception of their body weight. Underestimation of body weight was more common than overestimation, especially in men, the older people, and those with low education level. The percentage of taking action to lose weight was inversely associated with men and old age, and positively associated with higher education level, higher BMI, and self-perception as “fat” (OR = 3.78 in men, OR = 2.91 in women). Only 26.1% of overweight/obese individuals took action to lose weight. The top two weight loss practices were to reduce the amount of food intake and exercise.

Conclusion

Overweight and obesity were highly prevalent with high incorrect body weight perceptions in the general adult population in Beijing. Weight loss practice was poor in overweight and obese individuals. Actions at multiple levels are needed to slow or control this overweight and obesity epidemic.     

Effects of a supraphysiological dose of testosterone on physical function, muscle performance, mood, and fatigue in men with HIV-associated weight loss

Testosterone increases fat-free mass (FFM) in men infected with human immunodeficiency virus (HIV), but its effects on muscle performance, physical function, mood, and quality of life are poorly understood. Sixty-one HIV-infected men with weight loss were randomized to receive weekly intramuscular injections of 300 mg of testosterone enanthate or placebo for 16 wk. The primary outcome of interest was physical function (walking speed, stair-climbing power, and load-carrying ability). Secondary outcome measures included body weight and composition, muscle performance, sexual function, mood, and quality of life. Serum nadir free and total testosterone levels increased (+188.0 +/- 29.6 and +720 +/- 86 ng/dl) in the testosterone, but not placebo, group. Testosterone administration was associated with increased FFM (2.8 +/- 0.5 kg), which was significantly greater than in the placebo group (P < 0.0001). Leg press strength increased significantly in testosterone-treated (P = 0.027), but not placebo-treated, men; the difference between groups was not significant. Other measures of muscle performance and physical function did not change significantly in either group. Men receiving testosterone demonstrated significantly greater improvements in mental health and quality-of-life scores than those receiving placebo and improvements in fatigue/energy and mood scores that were not significantly different from those receiving placebo. Sexual function scores did not change in either group. In HIV-infected men with weight loss, a supraphysiological dose of testosterone significantly increased FFM but did not improve self-reported or performance-based measures of physical function. Improvements in mood, fatigue, and quality-of-life measures in the testosterone group, although clinically important, need further confirmation.     

Citizens' advice in general practice.

OBJECTIVE--To examine the introduction of citizens advice bureau sessions into general practice. DESIGN--Prospective survey of 150 consecutive attenders. SETTING--10 Practices in south Birmingham that volunteered to participate. OUTCOME MEASURES--The social characteristics of the population attending, the problems presented, the social security and other payments obtained, and the health problems mentioned during the sessions. RESULTS--Advice requested covered the whole range offered by the citizens advice bureaus. Thirty nine of 150 attenders obtained payments totalling 58,300.58 pounds for year 1991-2, of which 54,929.58 pounds was recurring. People mentioning health problems were significantly more likely to be entitled to unclaimed benefits. CONCLUSIONS--The provision of citizens advice bureau sessions in general practice is an effective way of providing advice on life problems and securing proper payment of benefits, particularly to patients with health problems. This service complements rather than detracts from other citizens advice bureau activities.
