Prospective breast cancer risk factors prediction in Saudi women

Women's health is affected by breast cancer worldwide and Saudi Arabia (SA) is no exception. Malignancy has enormous consequences for social, psychological and public health. The aim of this study was to examine the risk factors for Saudi women from breast cancer using logistic regression models. In 135 patient cases for different stages of breast cancer was used to study case management, 270 healthy women from King Abd Alla Medical City, Mecca, SA were taken to predict the probability of women developing breast cancer, logistic regression was analyzed taking factors such as age, marital status, family history, parity, age at first full-term pregnancy, menopausal status, body mass index (BMI) and breast feeding. The logistic regression model showed that there are important risk factors (age, marital status, family history, parity, age at first full-term pregnancy, menopausal status, body mass index, and breast feeding) in development of breast cancer. Fewer cases were observed in unmarried women, age ≤30, BMI ≤20. In contrast, more cases were found with women age 41–50 married, BMI > 30, a smaller number of children, not breast feeding, age of first pregnancy ≥30, menopausal status age at 46–50. Based on our data there is role of risk factors in developing breast cancer, less BMI, the increase number of children, breast feeding, which are playing as protective factor for breast cancer.     

Reproductive events and family history as risk factors for breast cancer in northern Alberta.

Reproductive events and family history as risk factors for breast cancer in northern Alberta were investigated with the use of data from a computerized population-based registry. Women aged 30 to 79 years attending diagnostic breast clinics at the Cross Cancer Institute from 1971 through 1975 constituted the two study groups; 1232 women had diagnosed breast cancer (malignant disease group) and 602 women were clinically free of all types of breast disease (control group). An increased relative risk of breast cancer was found in women with a family history of breast cancer, those who gave birth to their first term infant at age 30 years or older, those in whom more than 15 years elapsed between menarche and that birth, and those with a late natural menopause. There was a decreased risk, relative to nulliparity, in the postmenopausal women who first gave birth to a term infant 5 years or less after menarche. Artificial menopause (bilateral oophorectomy), parity and age at menarche had no apparent effect on the risk. The pattern of risk factors in northern Alberta differed from that reported for other geographic areas, including other provinces of Canada, thus emphasizing the need for local studies in the planning of screening programs.     

Spontaneous abortion and subsequent Down syndrome livebirth

Summary Analyses of two data sets are presented, one based on nationwide hospital discharges for the USA for 1970–1971, the other for Upstate New York vital record data for 1976–1981. Summary relative risks of a Down syndrome livebirth were calculated within the three maternal age categories below 20, 20–29, and 30 years and above for those with a history of one spontaneous abortion and for those with a history of two or more, compared to those with no reported previous abortions. There was significant heterogeneity by age and reproductive history in the relative risk of an affected child. In general the trends revealed that the younger the mother and the more the number of abortions, the higher the relative risk of a Down syndrome livebirth compared to the rates for women of the same age for those with no previous abortions. Extrapolation from average maternal age specific rates on Down syndrome imply a rate per 1000 livebirths somewhere in the range of 1.1 to 11.4 for women under 20 years with a history of one spontaneous abortion, of 5.2 to 13.4 for women under 20 years with a history of two or more spontaneous abortions, and of 1.0 to 2.4 for women 20 to 29 years with a history of two or more spontaneous abortions. (Average background livebirth rates in women under 30 years are, in contrast, in the range of about 0.5 to 1.0 per 1000 and for the average woman aged 35 years, at which prenatal diagnosis is usually felt to be indicated, 2.7 per 1000.) For those in the other categories these data did not reveal clinically significant effects upon average maternal age specific rates. It is emphasized that because of limitations in the data it is not possible to refine these risks by adjusting for karyotype, the age at which the abortions occurred, or other biologic and social factors associated with embryonic and fetal death. The implications of the analyses here for genetic counseling should be regarded as preliminary and tentative.     

Who remains childless?

Who are the men and women who are childless in their mid-30s? Life history data for a British cohort born in 1946 show that age at marriage and marital breakdown were clearly associated with childlessness. Women who were only children were more likely to be childless than those with siblings. Further, early menarcheal age, being highly qualified and having a high status occupation were indirectly related to childlessness. For men, particularly amongst those who had experienced a broken marriage, it was the most ambitious, the highly educated and those in professional occupations who were relatively more likely to be childless.     

Prevalence of gallstones and gallbladder disease in Canadian Micmac Indian women.

The prevalence of gallstones and gallbladder disease was studied between October 1973 and June 1976 in Canadian Micmac Indian women aged 15 to 50 years in an inland rural community near Shubenacadie, NS. Of 132 women at risk 98 underwent cholecystography, 6 had a history of cholecystectomy (verified from hospital records) and 3 had cholecystectomy because of cholecystitis during the 3 years of the study. Of the 17 abnormal cholecystograms 10 showed radiolucent gallstones, and repeated studies documented gallstones in 6 of the 7 radiographs on which the gallbladder was not visualized. The prevalence of gallstones was found to be 211/1000, and that of gallbladder disease, 240/1000. The peak prevalence was at 30 to 39 years of age. The women with gallbladder disease were significantly more obese and of greater parity than those without gallbladder disease even when age was controlled. The Micmac Indian women of Nova Scotia appear to be at a much higher risk for the development of cholesterol gallstones and gallbladder disease than Caucasian women in Framingham, Massachusetts.     

Age at First Delivery and Osteoporosis Risk in Korean Postmenopausal Women: The 2008–2011 Korea National Health and Nutrition Examination Survey (KNHANES)

It has been reported in several studies that there may be a significant correlation between reproductive history and the risk of osteoporosis due to the effect of estrogen. Under this hypothesis, however, it is unclear whether the age at first delivery has any major influences on the risk of osteoporosis. Therefore, this study aimed to investigate the relationship between the age at first delivery and the risk of osteoporosis in Korean menopausal women. This study was performed using data from the 2008–2011 Korea National Health and Nutrition Examination Survey and included 2,530 Korean postmenopausal women. The diagnosis of osteoporosis was made using the World Health Organization T-score criteria (T-score ≤ -2.5, at the femoral neck or lumbar spine). Participants were categorized into 3 groups according to age at first delivery: ≤23, 24–29, and ≥30 years. Older age, lower body mass index, lower calcium intake, later menarche, and earlier menopause increased the risk of osteoporosis, whereas hormone therapy and oral contraceptive use were associated with a decreased risk of osteoporosis. Postmenopausal women whose first delivery occurred at age 24–29 years were shown to have a significantly increased risk of osteoporosis (odds ratio, 2.124; 95% confidence interval, 1.096–4.113; P = 0.026) compared to those who first gave birth after the age of 30 years. These findings suggest that postmenopausal women whose first delivery occurred in their mid to late 20s, a period during which bone mass slowly accumulates to the peak, are at an increased risk of osteoporosis.     

Fertility patterns after appendicectomy: historical cohort study

Surgical exploration for suspected appendicitis is the most common acute abdominal operation in children and young adults. However, in 20-30% of such explorations, the appendix is not inflamed. It is commonly thought that a perforated appendix may result in tubal dysfunction because of peritoneal adhesions after inflammation and a subsequent increased risk for extrauterine pregnancy and female infertility. Findings are reported from an examination of fertility patterns in women who had their appendix removed in childhood. 9840 women under age 15 years when they underwent appendicectomy between 1964 and 1983 were age-matched with 47,590 control women from the Swedish general population and followed until 1994. Women with a history of perforated appendix had a similar rate of first birth as the control women, as well as a similar distribution of parity at the end of follow-up. Women who had had a normal appendix removed had an increased rate of first births, and on average had their first child at an earlier age and reached a higher parity than control women. These findings therefore suggest that a history of perforated appendix in childhood does not seem to have long-term negative consequences upon female fertility.     

Life History of Female Preferences for Male Faces

Although scientific interest in facial attractiveness has developed substantially in recent years, few studies have contributed to our understanding of the ontogeny of facial preferences. In this study, attractiveness of 30 male faces was evaluated by four female groups: girls at puberty, nonpregnant and pregnant young women, and middle-aged women. The main findings are as follows: (1) Preference for sexy-looking faces was strongest in young, nonpregnant women. (2) Biologically more mature girls displayed more adultlike preferences. (3) The intragroup consistency for postmenopausal women was relatively low. (4) In terms of the preference pattern, pregnant women were more similar to perimenopausal women than they were to their nonpregnant peers. (5) Preference for youthful appearance decreased with the age of the women. I argue that the life history of female preferences for male faces is, to a large extent, hormone-driven and underpinned by a set of evolutionary adaptations.     

Biological and behavioral determinants of fertility in Tierra del Fuego

The reproductive history of 182 women in postreproductive life or near menopause from the Chilean part of Tierra del Fuego was traced back by means of familial interviews. These postmenopausal women represent the population since almost the beginning of the settlement, and their reproductive years were spent on the island. Path analysis was applied to analyze fertility determinants of these women and to propose a complex model of interconnections among factors. The reproductive history of these women is characterized by a long fertile span, a short childbearing period, and low fertility. Age at menarche is relatively late, and the age of the women at first birth is mainly determined by their late age at marriage. The use of contraception is related to both spacing and stopping behaviors. The late age of women at marriage, the rhythm of conception, and practices of contraception are proposed as the main determinants of fertility in Tierra del Fuego.     

The muscle-bone unit in adulthood: influence of sex, height, age and gynecological history on the bone mineral content and muscle cross-sectional area

Bone and muscle development are both strongly influenced by sex hormones. The purpose of this study was to examine the changes in bone and muscle parameters (bone mineral content - BMC, muscle cross-sectional area - MA) in 130 men aged 31 -60 years, and in 180 pre-menopausal women aged 30-53 years with respect to age, body height and, with the women, their gynecological history (age-at-menarche, number of pregnancies, duration of lactation and use of oral contraception). The study was performed using peripheral quantitative computed tomography (pQCT) at a 65% site of the forearm length. Both BMC and MA were dependent on body height (p<0.0001), but not on age. The BMC/MA ratio was dependent neither on age nor on body height in both genders. MA as well as BMC were found significantly higher in males than in females (p<0.0001 for both variables). We observed a significantly higher BMC/MA ratio in females than in males (p<0.0001). We found no effect either of the analyzed variables of gynecological history on bone/muscle characteristics. The findings highlight the necessity of involving height-adjusted parameters and BMC/MA ratio into bone analysis in adults.     

The association between sociodemographic,hormonal, tubo-ovarian factors and bacterial count in Chlamydia and Mycoplasma infections with infertility

Aim: To determine if there is an association between the Chlamydia and Mycoplasma infections with socio-demographic and clinical factors, and also with infertility. Methods: We conducted a study on 100 infertile married women and 100 control group, and collected data on the socio-demographic, hormonal and tubo-ovarian factors. The results of the endocervical swabs were analyzed for Mycoplasma and Chlamydia infection, the bacterial counts were also determined. Results: The percentage positivity to infection was significantly more among the infertile group compared to the control group, and also significantly more among the age group <30 years old. The positivity for infection with Chlamydia and/or Mycoplasma was significantly correlated with age, history of irregular menstruation, and history of previous abortion. Further sub-analysis of the infertile group showed that positivity to Chlamydia and/or Mycoplasma infection was significantly correlated to hormonal factors, ovarian factors, irregular menstruation, and previous abortion. Regression analysis showed that hormonal, ovarian factors, and irregular menstruation were the most significant factors in the positivity to Chlamydia and Mycoplasma infection. Bacterial count was significantly correlated with age, history of irregular menstruation, and history of previous abortion. Conclusion: Infection to Chlamydia and Mycoplasma is associated to younger age (?30 years old), and occurs in the infertile women. There is an interplay between infection in younger women, irregular menstruation, hormonal, and tubo-ovarian factors with infertility. Bacterial count was significantly correlated with age, history of irregular menstruation, and history of previous abortion.     

Clinical Significance of Dysuria in Women

During a community survey 22% of women were found to have had dysuria in the previous year and half had had dysuria at some time in their lives. Various measurements were made in a random sample of 282 of these women. The means and the variances of the systolic and diastolic blood pressures in women with a past history of dysuria tended to be higher than in women who gave no such history. There were no significant differences in the means of plasma urea, plasma creatinine, and renal concentrating power between women with and without a previous history of dysuria, but a significant impairment of renal concentrating power was found in an additional group of 30 women who dated the onset of their dysuria to childhood.These findings suggest that urinary tract infection in adult women does not usually lead to progressive impairment of kidney function, whereas infection in childhood is more often associated with kidney damage.     

Risk of Cardiovascular Events in Mothers of Women with Polycystic Ovary Syndrome

ObjectiveTo assess the prevalence of cardiovascular events in an older population of women with polycystic ovary syndrome (PCOS).MethodsWe took advantage of the high heritability of PCOS and determined the probable PCOS status of mothers of women with PCOS. The prevalence of cardiovascular events was then determined in these mothers with and without PCOS. In a single endocrine clinic, 308 women with PCOS were interviewed about their mothers’ medical history, and the mothers themselves were interviewed if available. The interview addressed menstrual history, fertility, clinical signs of hyperandrogenism, age at incident cardiovascular event, and age at death as reported by daughters. Presence of PCOS in the mothers was defined as a history of infertility, irregular menses, or clinical signs of hyperandrogenism. A cardiovascular event was defined as fatal or nonfatal myocardial infarction, any coronary intervention, angina necessitating emergency department visits, or a cerebrovascular event.ResultsThe mothers were predominantly postmenopausal. Among 182 interviewed (n = 157) or deceased (n = 25) mothers, 59 had probable PCOS. Cardiovascular events were more common (P = .011) among mothers with PCOS (11 of 59 or 18.6%) than among non-PCOS mothers (5 of 123 or 4.1%). After adjustments were made for age and race, probable PCOS was an independent predictor of cardiovascular events (odds ratio, 5.41; 95% confidence interval, 1.78 to 16.40). Cardiovascular events occurred at an early age in mothers of women with PCOS, particularly mothers with probable PCOS themselves.ConclusionPCOS-affected mothers of women with PCOS have a higher risk for cardiovascular events in comparison with non-PCOS mothers, and cardiovascular events appear to occur at an earlier than expected age in mothers with PCOS.

The value of needle aspiration cytology of the breast, with an emphasis on the diagnosis of breast disease in young women below the age of 30

Our experience with 4,739 needle aspirations of the breast was reviewed, with an emphasis on the diagnosis of carcinoma in young women under the age of 30 years. Among benign diseases, fibroadenomas were most frequently seen in younger women (24.3% of 919 cases) while cysts were most frequently seen in women 30 years of age and older (20.0%). Fibrocystic conditions were identified in approximately 30% of the women in each group. All younger women with suspicious diagnoses had fibrocystic disease at biopsy; in older women, 75% of the suspicious cases proved to be carcinomas while 25% proved to be fibrocystic diseases. Carcinomas were diagnosed cytologically in 1.3% of younger women and in 9.7% of older women. In young women, in whom breast carcinoma is a rare disorder, it is important that carcinoma be diagnosed without delay so that an appropriate plan of management can be adopted. These findings suggest that needle aspiration cytology can accurately make that diagnosis.     

Prevalence of risk factors associated with human papillomavirus infection in women living with HIV

BACKGROUND: Concurrent infection with HIV and human papillomavirus (HPV) in women is associated with increased rates of cervical dysplasia and shorter survival following the development of cervical cancer. The authors examined risk factors for HPV infection at study entry in HIV-positive women enrolled in the Canadian Women''s HIV Study, a prospective open cohort study. METHODS: Subjects eligible for this analysis included the 375 HIV-positive women in the Canadian Women''s HIV Study for whom HPV test results were available. Questionnaires on behavioural and clinical information, Pap smears, cervicovaginal lavage specimens and vaginal tampon specimens for HPV detection and typing by polymerase chain reaction were obtained at study entry. RESULTS: Overall, 67.2% (252/375) of the women were HPV-positive; the global prevalence of intermediate- and high-risk oncogenic HPV types was 49.1% (184/375). Women with squamous cell dysplasia (32/294) were more likely to have HPV infection than those without dysplasia (90.6% v. 62.6%; p = 0.002). Multivariate logistic regression analysis, with adjustment for number of lifetime partners and history of STD, revealed that the following risk factors were independently associated with HPV infection: CD4 count of less than 0.20 x 10(9)/L (adjusted odds ratio [OR] 1.99 [95% confidence interval (Cl) 1.17-3.37 (p = 0.011)]), non-white race (adjusted OR 2.00 [95% Cl 1.17-3.42 (p = 0.011)]), inconsistent condom use in the 6 months before study entry (adjusted OR 2.02 [95% Cl 1.16-3.50 (p = 0.013)]), and lower age, with women age 30-39 years (adjusted OR 0.51 [95% Cl 0.30-0.87 (p = 0.013)]) and age 40 years or older (adjusted OR 0.52 [95% Cl 0.26-1.01 (p = 0.052)]) compared with women less than 30 years of age. INTERPRETATION: Close monitoring for HPV-related effects is warranted in all HIV-positive women, particularly younger, non-white women who do not always use condoms. Counselling for women living with HIV, particularly younger women, should emphasize the importance of regular cytological screening, with increasing frequency as the CD4 count falls.     

高龄孕妇分娩新生儿出生体重及出院转归的影响因素分析

摘要 目的：探讨高龄孕妇分娩新生儿出生体重及出院转归的影响因素。方法：选择2021年01月到2022年01月与我院就诊的198例产妇作为研究对象,根据孕妇分娩时的年龄分为观察组和对照组,分娩时年龄满35周岁为高龄产妇组（98例）,分娩时年龄为20~34周岁为适龄组（100例）。比较适龄孕妇和高龄孕妇新生儿出生体重情况和新生儿住院时间,对高龄孕妇新生儿体重和新生儿出院转归影响因素进行Logistic单因素分析和多因素分析。结果：与适龄孕妇相比,高龄孕妇新生儿低出生体重儿、巨大儿发生率更高（P<0.05）,新生儿住院时间明显更长（P<0.05）。对高龄孕妇新生儿体重进行单因素分析结果显示,妊娠糖尿病、产检检查、分娩方式、是否使用催产素、分娩时麻醉方式和脐带情况与高龄孕妇新生儿体重无关（P>0.05）,孕妇年龄、孕前BMI、孕期体重增加情况、妊娠高血压、合并其他疾病状况、孕次、产次、羊水情况与高龄孕妇新生儿体重相关（P<0.05）。进行Logistic多因素回归分析结果显示,孕妇年龄、孕前BMI、孕期体重增加情况、孕次、产次、羊水情况是影响高龄孕妇新生儿出生体重的独立危险因素（P<0.05）。对新生儿出院转归情况进行单因素分析结果显示,胎次、开奶时间、喂养方式和有无接受治疗与新生儿出院转归无相关性（P>0.05）,胎龄、出生体重、Apgar评分、出生窒息史、有无伴发疾病与新生儿转归相关（P<0.05）。进行Logistic多因素分析结果显示,胎龄、出生体重、Apgar评分、出生窒息史、有无伴发病是影响新生儿出院转归的独立危险因素（P<0.05）。结论：孕妇年龄、孕前BMI、孕期体重增加情况、孕次、产次、羊水情况是影响高龄孕妇新生儿出生体重的独立危险因素。新生儿出院转归受到胎龄、出生体重、Apgar评分、出生窒息史、有无伴发病影响。     

Risk assessment adjusted for gestational age in maternal serum screening for Down's syndrome.

OBJECTIVE--To investigate the relation between errors in calculation of gestational age and assessment of risk of Down''s syndrome and to analyse the implications for screening programmes. DESIGN--Retrospective analysis of dating of gestational age by menstrual history v ultrasound scan. Computer program with maternal age and concentrations of alpha fetoprotein and free beta human chorionic gonadotrophin to calculate risk for a range of expected dates of delivery. Computer simulated prospective application of new screening programme. SETTING--Teaching hospitals in Nottingham. SUBJECTS--31,561 women with singleton pregnancies with gestational age based on routine ultrasound scan. Computer simulation of 20,000 women in three age ranges (up to 37; up to 40; all). MAIN OUTCOME MEASURES--Distribution of error between gestational age based on ultrasound scan v menstrual history. Proportion of women in the population who require precise dating of pregnancy; proportion of women who require amniocentesis. RESULTS--With gestational age derived from ultrasound scan as reference the 95% confidence interval for gestational age by menstrual history was -27 to +9 days. A screening programme for Down''s syndrome for women up to age 40 would yield a low risk (< 1:250) for this range of days in 86.0% of cases. The 14.0% of women remaining would have one or more high risk values in their report and would thus require an ultrasound scan for precise dating of the pregnancy; 30% of these--that is, 3.7% of the screened population--would be identified as high risk and require consideration for amniocentesis. CONCLUSIONS--Screening programmes for Down''s syndrome require the facility for precise dating of pregnancy to improve the accuracy of risk assessment. This can be achieved without introducing additional scans for early dating in the whole population but by selecting only those cases (about 14%) when an error in dates is likely to affect the risk of Down''s syndrome.     

Maternal age at last birth in Egypt

To assess the effects of women's education, residence, and marital experience on their age at the birth of their last child, a proportional hazards regression model was applied to 1980 Egyptian Fertility Survey (EFS) data. The detailed data include the date of birth of each child for every women interviewed, and the woman's date of birth and age at interview. Age at last birth was examined by regression analysis on birth history and socioeconomic information. 4 hypotheses were tested: women who are well educated have a greater probability of ending childbearing earlier than women with less education; women in rural areas have a higher probability of having their last child at older ages than urban women; marital disruption without remarriage lowers the probability of older maternal age at last birth; and marital disruption with remarriage increases the probability that a woman stops reproducing at an older age. The overall chi-square indicates a significant regression. All coefficients were significant, except the coefficient for women with intact 1st marriages. Women with more education had a greater probability of ending childbearing earlier than women with less education. Rural women tended to have their last children at ages significantly older than overall age at last birth. Current residence in urban areas had the opposite effect. The coefficient for those with intact 1st marriages was insignificant, meaning that the mean age at last birth for this group of women was not much different from the overall mean. Remarried women tended to end childbearing at ages significantly older than the overall average age at last birth, suggesting that these women tended to have children by their new husbands. Those with dissolved 1st marriages who had not remarried had a higher probability of ending childbearing earlier than did older women. Marriage age and final parity had highly significant negative coefficients; as marriage age and number of children born increased, so did the "survival" time or the age at last birth. Results from the hazards model indicate that the effects were as anticipated. The median age at last birth for the total sample of women aged 45-49 was 45-49 years. The median age at last birth was about 2 years older for rural compared to urban women. Illiterate women had the oldest median age at last birth of the education groups. There was little differences between median ages at last birth for women with intact 1st marriages and those whose 1st unions were dissolved and who had remarried. The median age at last birth increased with final parity.     

Human papillomavirus vaccination for adults aged 30 to 45 years in the United States: A cost-effectiveness analysis

BackgroundA nonavalent human papillomavirus (HPV) vaccine has been licensed for use in women and men up to age 45 years in the United States. The cost-effectiveness of HPV vaccination for women and men aged 30 to 45 years in the context of cervical cancer screening practice was evaluated to inform national guidelines.Methods and findingsWe utilized 2 independent HPV microsimulation models to evaluate the cost-effectiveness of extending the upper age limit of HPV vaccination in women (from age 26 years) and men (from age 21 years) up to age 30, 35, 40, or 45 years. The models were empirically calibrated to reflect the burden of HPV and related cancers in the US population and used standardized inputs regarding historical and future vaccination uptake, vaccine efficacy, cervical cancer screening, and costs. Disease outcomes included cervical, anal, oropharyngeal, vulvar, vaginal, and penile cancers, as well as genital warts. Both models projected higher costs and greater health benefits as the upper age limit of HPV vaccination increased. Strategies of vaccinating females and males up to ages 30, 35, and 40 years were found to be less cost-effective than vaccinating up to age 45 years, which had an incremental cost-effectiveness ratio (ICER) greater than a commonly accepted upper threshold of $200,000 per quality-adjusted life year (QALY) gained. When including all HPV-related outcomes, the ICER for vaccinating up to age 45 years ranged from $315,700 to $440,600 per QALY gained. Assumptions regarding cervical screening compliance, vaccine costs, and the natural history of noncervical HPV-related cancers had major impacts on the cost-effectiveness of the vaccination strategies. Key limitations of the study were related to uncertainties in the data used to inform the models, including the timing of vaccine impact on noncervical cancers and vaccine efficacy at older ages.ConclusionsOur results from 2 independent models suggest that HPV vaccination for adult women and men aged 30 to 45 years is unlikely to represent good value for money in the US.

Jane Kim and co-workers estimate the potential cost-effectiveness of papillomavirus vaccination for adults aged 30-45 years in the United States.     

Role of Weight History on Functional Limitations and Disability in Late Adulthood: The ARIC Study

Objective: To examine associations of weight history with functional limitations and disability in white and African‐American men and women. Research Methods and Procedures: Data were from the Atherosclerosis Risk in Communities study (n = 11, 177). Associations of recalled weight status at age 25 and weight change from age 25 to ages 45 to 64 with functional limitations, activities of daily living (ADLs), and instrumental activities of daily living (IADLs) at follow‐up (ages 52 to 75) were examined using logistic regression. Results: Obesity (BMI ≥ 30 kg/m²) at age 25 was associated with functional limitations and ADL and IADL impairment at follow‐up in white and African‐American men and women. For example, obese compared with normal weight (BMI, 18.5 to 24.9 kg/m²) white women had higher odds of mild [odds ratio (95% confidence interval), 1.97 (1.18 to 3.29)] and severe [9.81 (5.92 to 16.27)] functional limitations and ADL [3.48 (2.36 to 5.13)] and IADL [2.95 (2.00 to 4.33)] impairment. In African‐American women, obesity was associated with higher odds of mild [2.71 (1.14 to 6.41)] and severe [6.01 (2.53 to 14.26)] functional limitations and ADL [1.82 (1.10 to 3.00)] and IADL [2.39 (1.47 to 3.90)] impairment. Similar associations were found in men. Compared with weight maintenance (±10 lbs), large weight gain (>30 lbs) from age 25 to ages 45 to 64 was also associated with functional limitations and ADL and IADL impairment in white and African‐American men and women. Discussion: Maintenance of a healthy body weight throughout adulthood may play a role in preventing or delaying the onset of functional limitations and disability, resulting in increased quality of life and decreased health care costs.
