Prevalence of overweight and obesity among urban and rural adult females of Punjab

The prevalence of overweight and obesity was assessed during a community based epidemiological survey on a randomized sample of 1700 (900 urban and 800 rural) adult Punjabi females in the age group from 20-45 years. For the assessment of overweight and obesity, height and weight measurements were taken on each subject. The prevalence rate of malnutrition was calculated according to the critical limits of body mass index (BMI). The observations show that the combined overall prevalence rate of overweight/obesity in the present study is 43.88% and 22.26%, respectively, for urban and rural females. The frequency of overweight and obesity is more among urban females than in their rural female counterparts.     

Recent trends in the prevalence of overweight and obesity among Canadian children

Background:Previous studies have shown an increase in the prevalence of overweight and obesity among Canadian children from 23.3% to 34.7% during 1978–2004. We examined the most recent trends by applying current definitions of overweight and obesity based on World Health Organization (WHO) body mass index (BMI) thresholds and recently validated norms for waist circumference and waist:height ratio.Methods:We examined directly measured height and weight data from the Canadian Community Health Survey (2004–2005) and the Canadian Health Measures Survey (2009–2013). We calculated z scores for BMI, height and weight based on the 2014 WHO growth charts for Canada, including the new extension of weight-for-age beyond 10 years. To calculate z scores for waist circumference and waist:height ratios, we used new charts from the reference population in the US NHANES III (National Health and Nutrition Examination Survey, 1988–1994).Results:Data were available for 14 014 children aged 3–19 years for the period 2004–2013. We observed a decline in the prevalence of overweight or obesity, from 30.7% (95% confidence interval [CI] 29.7% to 31.6%) to 27.0% (95% CI 25.3% to 28.7%) (p < 0.001) and stabilization in the prevalence of obesity at about 13%. These trends persisted after we adjusted for age, sex and race/ethnicity. Although they declined, the median z scores for BMI, weight and height were positive and higher than those in the WHO reference population. The z scores for waist circumference and waist:height ratio were negative, which indicated that the Canadian children had less central adiposity than American children in historic or contemporary NHANES cohorts.Interpretation:After a period of dramatic growth, BMI z scores and the prevalence of overweight or obesity among Canadian children decreased from 2004 to 2013, which attests to progress against this important public health challenge.Ongoing pan-Canadian surveys such as the Canadian Community Health Survey (CCHS) and Canadian Health Measures Survey (CHMS) are important to evaluate the health of our population using representative national samples.^1,2 Self-reported heights and weights replaced direct measurement during 1978–2004, which underestimated true rates of overweight and obesity.³ A subsequent comparison of directly measured heights and weights during the same period showed an alarming increase in the prevalence of overweight or obesity among Canadian children aged 2–17 years, from 23.3% (95% confidence interval [CI] 20.5% to 26.0%) to 34.7% (95% CI 33.0% to 36.4%) based on the new World Health Organization (WHO) definitions.¹In Canada, the definitions of overweight and obesity changed with the introduction of the 2010 WHO growth charts for Canada.^4,5 Previous definitions were based on body mass index (BMI) percentiles from the 2000 US Centers for Disease Control and Prevention (CDC) growth charts.⁶ In addition to revising these percentile thresholds, the WHO charts were based on a different reference population; as a result, the proportion of Canadian children classified as overweight or obese increased with the introduction of the new WHO charts.^1,7,8 Moreover, the absolute percentile thresholds now vary by age, with toddlers (2 to ≤ 5 yr) having higher thresholds to define overweight and obesity than older children (age > 5 to 19 yr).⁴Results from the United States have shown a decline in obesity rates among toddlers and a plateau in rates among older children;^9,10 stabilization has also been noted in other jurisdictions (e.g., Germany and Australia).^11–16 We undertook this study to determine the most recent trends in the prevalence of overweight and obesity among Canadian children using the current WHO weight charts for Canada applied to a representative sample of children.     

Trends of overweight and obesity among white and american indian school children in south dakota, 1998–2010

Objective:

To investigate the prevalence of overweight and obesity among white and American Indian children in a predominantly rural state.

Design and Methods:

Using a repeated, cross‐sectional design of school children's height and weight, the study sample included 361,352 measures of children who were 5.0–19.9 years, attending school across 13 academic calendar years. Trained staff measured height, weight, and recorded gender, age, and race. Data were voluntarily reported to the State Department of Health.

Results:

American Indian children consistently had higher rates of overweight and obesity compared to white children. Across the years, 16.3% of white students were overweight, whereas 19.3% of American Indian students were overweight. In addition, 14.5% of white children were obese and 25.9% of American Indian children were obese. Examining by rural versus urban schools, prevalence of overweight had been increasing among white male and female students and American Indian female students living in rural areas. Obesity is also increasing among rural white females and male and female American Indian children.

Conclusions:

The findings here suggest that although American Indian children are at higher risk, in general, compared to white children, rural populations in general are experiencing increases in childhood overweight and obesity. Targeted rural interventions beginning at an early age are necessary to improve the health of rural children, especially in American Indian communities.     

Prevalence of overweight and obesity in 2- to 6-year-old Italian children

Objective: To assess the prevalence of overweight and obesity in 2‐ to 6‐year‐old Italian children and to compare the prevalence between the north and the south of the country. Research Methods and Procedures: This was a cross‐sectional study of 2150 subjects (M/F: 1137/1013), 5.36 ± 0.83 years of age. The sampling areas were Verona (north Italy) and Messina (south Italy). We used definitions of overweight and obesity using BMI values, with cut‐off values proposed by the International Obesity Task Force. Results: The prevalence of overweight was 16.6% (males: 13.9%, females: 19.6%), and it was higher in the south (males: 17.8%, females: 22.4%) than in the north (males: 11.3%, females: 17.9%). The prevalence of obesity was 8.0% (males: 8.3%, females: 7.7%), and it was higher in the south (males: 12.3%, females: 10.7%) than in the north (males: 5.7%, females: 5.8%). Using the Centers for Disease Control reference charts, the prevalence of overweight and obesity of Italian children was close to that reported in children living in the United States (32% vs. 32.7%, respectively). Discussion: The prevalence of overweight and obesity in young Italian children is very high, and it is rapidly growing. In the south of the country, the prevalence is higher than in the north.     

Food consumption, activity, and overweight among elementary school children in an Appalachian Kentucky community

In the U.S., child overweight is on the rise and is implicated in later adult chronic illness. Given that overweight is hardly tractable, prevention as compared to treatment is seen as a better alternative for lowering the risk of long-term health consequences. To increase the success of prevention efforts, many argue that programs must be "culturally sensitive and targeted toward specific populations at greater risk. However, there exists a limited understanding of how overweight is distributed across the landscape, among and within populations and groups. This paper reports the prevalence of overweight among 54 school children in a rural, Appalachian community with a high rate of poverty, and it compares boys to girls. Thirty-seven percent of boys and 10.3% of girls are overweight, based on the 90th percentile body mass index (BMI). Analysis of food intake indicates a pattern of food consumption that is high in fatty and sugary foods and low in fruit and vegetable consumption. Analysis of activity indicates that children report more low-intensity activity than high; that overweight children report more episodes of video/computer play compared to nonoverweight children; and that boys spend more time than girls in front of the computer/television screen.     

Prevalence of the three categories of handedness among Malawian school children

A cross sectional study of prevalence of left, right and mixed handedness was made on 512 Malawian school children (240 boys and 272 girls) aged 6-17 years. Handedness was assessed using questionnaire incorporating questions on hand preferred for eight unimanual activities. Interviews with guardians, pupils and teachers were conducted to assess the pressure experienced by children to use right hand for unimanual activities. The overall prevalence of left-, right- and mixed-handers was 3.9%, 90.4% and 5.7%, respectively. Association between handedness and age or gender of children was nonsignificant. 96.2% of guardians and 92.7% of teachers were insistent upon use of right hand for unimanual tasks. Most of non-right handed children indicated that they had experienced pressure to use right hand for unimanual activities but they were still using left hand for one or more manual tasks. 28 pupils indicated that they stopped using left hand under the pressure from guardians and teachers.     

Prevalence and risk factors of overweight and obesity in China

Objective: To examine the prevalence and risk factors of overweight and obesity in China. Research Methods and Procedures: A cross‐sectional survey was conducted in a nationally representative sample of 15,540 Chinese adults in 2000–2001. Body weight, height, and waist circumference were measured by trained observers. Overweight and obesity were defined according to the World Health Organization classification. Central obesity was defined according to guidelines of the International Diabetes Federation. Results: Mean BMI and waist circumference were 23.1 kg/m² and 79.6 cm, respectively, for men and 23.5 kg/m² and 77.2 cm, respectively, for women. The prevalences of overweight and obesity were 24.1% and 2.8% in men and 26.1% and 5.0% in women, respectively. The prevalence of central obesity was 16.1% in men and 37.6% in women. The prevalences of overweight, obesity, and central obesity were higher among residents in northern China compared with their counterparts in southern China and among those in urban areas compared with those in rural areas. Lifestyle factors were the most important risk factors to explain the differences in overweight and central obesity between northern and southern residents. Among women, lifestyle and diet were the most important risk factors to explain the differences between urban and rural residents, whereas socioeconomic status, lifestyle, and diet were all important among men. Discussion: Our study indicates that overweight and obesity have become important public health problems in China. Environmental risk factors may be the main reason for regional differences in the prevalence of overweight and obesity in China.     

Prevalence of urogenital and intestinal schistosomiasis among school children in South-west Nigeria

BackgroundThe risk of co-infection with Schistosoma haematobium and S. mansoni and the potential harmful effect on morbidity and control is enhanced by the overlapping distribution of both species in sub-Saharan Africa. Despite the reported high endemicity of both species in Nigeria, studies on the spread and effect of their mixed infection are limited. Therefore, a cross-sectional survey was conducted among school children in two communities in South-west Nigeria to investigate the prevalence of mixed human schistosome infection, intensity, and possible ectopic egg elimination.MethodsUrine and stool samples were collected from consenting school children in Ilie and Ore communities of Osun State, Nigeria. Schistosoma haematobium eggs were detected in urine using the urine filtration technique, while S. mansoni eggs were detected in stool using the Kato–Katz thick smear technique.ResultsThe study enrolled 466 primary and secondary school children (211; 45.3% males vs. 255; 54.7% females; mean age 11.6 ± 3.16 years). The overall prevalence of schistosomiasis was 40% (185/466), with 19% (89/466) recording single S. haematobium infection while 9% (41/465) had a single S. mansoni infection. The geometric mean egg count for S. haematobium was 189.4 egg/10ml urine; 95% CI: range 115.9–262.9, while for S. mansoni, it was 115.7 epg; 95% CI: range 78.4–152.9. The prevalence of ectopic S mansoni (S. mansoni eggs in urine) was 4.7%, while no ectopic S. haematobium (S. haematobium eggs in stool) was recorded. Mixed infection of S. haematobium/S. mansoni had a prevalence of 9.5% (44/466). More females (54.5%) presented with S. haematobium/S. mansoni co-infection. For both parasites, males had higher infection intensity, with a significant difference observed with S. haematobium (p = 0.0004). Hematuria was significant in individuals with single S. haematobium infection (p = 0.002), mixed ectopic S. haematobium/S. mansoni (p = 0.009) and mixed S. haematobium/S. mansoni/ectopic S. mansoni (p = 0.0003).ConclusionsThese findings suggest the probability of interspecific interactions between S. haematobium and S. mansoni. Scaling up of mass administration of praziquantel and control measures in the study areas is highly desirable.     

Behavioral pattern of overweight and obese school children

The aim of this study was to determine socio economic, health status, nutritional and behavioral differences in obese, overweight and normal weight children attending first grade elementary school. In overweight group there is 13.8% of boys and 12.6% of girls, in obese group 8.3% of boys and 6.9% of girls. In factor analysis 12 factors was excluded with cumulative loading of 60% variability. Discriminant analysis was performed with 12 factors as predictive variables and discriminant variables were three BMI groups: normal weight, overweight and obese. Function 1 discriminate well normal weight group from overweight and obese group. Overweight and obese groups is described with lower number of children in the family and lower order of birth, higher education of parents, they eat less vegetables and fruits, spend more time playing computer games, have less physical activity, drink more alcohol with their meals, exactly opposite to normal weight group.     

Predicting treatment initiation in a family-based adolescent overweight and obesity intervention

Little is known about factors associated with treatment initiation in overweight and obese adolescents. This study investigated parent-reported adolescent demographic, adolescent health, and parent motivation factors associated with initiation of a family-based adolescent overweight and obesity intervention. A telephone survey was completed by 349 parents calling to register their interest in participating in a cognitive behavioral lifestyle intervention for adolescent overweight and obesity. A total of 172 families (49.3%) returned their consent form to initiate treatment. A binomial logistic regression, with predictors entered in three blocks: (i) adolescent demographic (adolescent age, gender, adolescent BMI-for-age z-score, parent BMI); (ii) adolescent health (perceived adolescent physical and mental health, presence of an adolescent physical health problem or mental health problem, medication intake); and (iii) parent motivation (perceived adolescent weight category, concern about adolescent weight, importance of adolescent weight, confidence in adolescent capacity to change weight, priority of adolescent weight loss, discrepancy between adolescent current and ideal weight, previous weight loss attempts), was significant (χ2 (16) = 35.19, P = 0.004) accounting for 12.4-16.5% (95% confidence interval) of treatment initiation variance. Parent-reported adolescent physical health problem, parent perception of adolescent weight category, parent priority of adolescent weight loss, and parent perception of discrepancy between adolescent current and ideal weight were significant in the model. These findings indicate that data collected at intake are associated with treatment initiation and highlight the role of assessing and enhancing treatment motivation from initial contact.

Parent- and adolescent-reported barriers to participation in an adolescent overweight and obesity intervention

This study explored reported barriers to treatment completion in a sample of adolescents and their parents who either completed or did not complete family-based cognitive behavioral lifestyle intervention for overweight and obese adolescents. The sample comprises 56 overweight or obese adolescents (52% female) aged 11.5-18.9 years (mean = 14.5, s.d. = 1.8) and a parent. 57% of families did not complete treatment and maintenance phases of the intervention. A telephone-administered questionnaire assessing barriers to participation was completed by 96% of adolescents and 91% of parent completers and 100% of adolescents and 94% of parent noncompleters. Adolescents and parents most commonly reported barriers to participation related to research demands, treatment approach, program components/strategies, practical barriers, and other individual/family demands. Parents also noted adolescent effort, parent-adolescent conflict, and adolescent unhappiness as barriers to participation. While both completers and noncompleters experienced barriers to participation, families who discontinued treatment reported experiencing more treatment barriers. Findings of the current study suggest that adolescents and parents may find it easier to participate in adolescent overweight and obesity interventions if research and out-of-session program demands are minimized, efforts are made to enhance adolescent motivation, and treatment is offered in a convenient location and scheduled around school holidays and other family demands. Results also suggest that targeting adolescent unhappiness, family stressors, and parent-adolescent conflict in treatment may improve retention. Future research should explore the impact of these modifications on treatment completion and outcomes.     

Hyperuricemia and metabolic syndrome in children with overweight and obesity

ObjectiveTo study the prevalence of hyperuricemia in children with overweight or obesity and analyze the relation with metabolic syndrome and the diseases that define it.Materials and methodsThis is a cross-sectional prevalence study in 148 children recruited from pediatric endocrinology consultation, with overweight or obesity (12 ± 3 years, 48% boys, BMI 31.8 ± 6.1). We measured BMI, waist-height, waist circumference, blood pressure with standard instrumentation and glucose (fasting and after overload with 75 g), insulin resistance, cholesterol HDL, triglycerides and uric acid.ResultsThe prevalence of hyperuricemia was 53%. Patients with hyperuricemia had greater BMI (33.9 vs 30.6, p = 0.003), plus waist circumference (101.4 vs 91.1 cm, p < 0.001), higher blood pressure: systolic (123.4 vs 111.9 mm Hg, p < 0.001), diastolic (78.2 vs 68.7 mm Hg, p < 0.001). They presented greater blood glucose after overload oral glucose (107.5 vs 100.7 mg/dl, p = 0.03), insulin was higher (29.2 vs 20.7 mg/dl, p = 0.001) as well as HOMA IR (6.5 vs 4.4, p < 0.001) and HDL levels were lower (49.5 vs 54.4 mg/dl, p = 0.02).Uric acid's level which most is the likely diagnosis of metabolic syndrome corresponds to 5.4 mg/dl in our sample (sensitivity: 64% and specificity 62%).ConclusionThe prevalence of hyperuricemia in children with overweight and obesity is high. In the group of patients with obesity and hyperuricemia, we found out that the parameters measured to diagnose with metabolic syndrome were less favorable. Uric acid's level from where there is a higher possibility to see metabolic syndrome is 5.4 mg/dl.     

Trends in the prevalence of overweight and obesity among young Australians, 1985, 1997, and 2004

Objective: To determine secular trends in overweight/obesity among 7‐ to 15‐year‐olds for the periods 1985, 1997, and 2004. Research Method and Procedures: Data from representative surveys conducted in New South Wales, Australia, in 1985, 1997, and 2004 were analyzed. Height and weight were measured, and BMI categories were created using International Obesity Task Force definitions. Students were grouped as Grades 2 + 4 + 6 and 8 + 10. Results: The prevalences of overweight/obesity for 1985, 1997, and 2004 were 10.9%, 20.6%, and 25.7% among the younger boys and 10.6%, 19.5%, and 26.1% among the older boys. The average annual rate of increase for 1985 to 1997 was 0.81% and for 1997 to 2004 was 0.73% among the younger boys and was 0.74% and 0.94% for the two periods among the older boys. The prevalences of overweight/obesity in 1985, 1997, and 2004 were 14.0%, 22.0%, and 24.8% among the younger girls and 8.3%, 17.9%, and 19.8% among the older girls, respectively. The average annual rates of increase for the two periods were 0.8% and 0.4% among the younger girls and 0.80% and 0.27% among the older girls. Change in the prevalence of overweight/obesity and socioeconomic status were not associated. Discussion: Over the period 1985 to 1997, the prevalence of overweight and obesity increased significantly among the younger and older boys and the younger girls. The prevalence of overweight, but not obesity, increased among the older girls over this period. Over the period 1997 to 2004, the prevalence of overweight/obesity combined increased significantly among boys of both age groups but not among girls.     

Prevalence and associated factors of overweight and obesity in a Chinese rural population

Background: Overweight and obesity are now considered as a serious health problem, and a very important risk factor for many diseases. Objective: This study was designed to investigate the epidemiologic features of overweight and obesity among rural adults in China. Method and Procedures: A cross‐sectional survey was conducted during 2004–2005, using a multistage cluster sampling method to select a representative sample in Fuxin county, Liaoning province, China. A total of 29,970 adults, aged ≥35 years, were examined. At baseline, lifestyle and other factors were obtained. Overweight and obesity were defined according to the classification by the World Health Organization. Results: Overall, the prevalence of overweight was 18.6%; 15.1% in men and 22.1% in women. The prevalence of obesity was 1.7%; 1.2% in men and 2.2% in women. Multivariable logistic regression revealed certain risk factors of obesity that included being a women, Mongolian nationality and education status of over junior high school level. Moderate physical activity alone was shown as protective factor. Discussion: Although the prevalence of obesity was low, overweight was relatively high in the Chinese rural population, especially in adult women. Gender, diet, physical activity, education levels, and ethnicity were associated with the prevalence of these health conditions.     

Social inequality and obesity in Czech school children

This study uses logistic regressions to consider the effect of social factors, physical activity, meal frequency and BMI of parents on children's body mass index (BMI) values. Three thousand three hundred and sixty-two children aged 7-11 years were examined in 38 schools in the Czech Republic. Six anthropometric characteristics were assessed in 1999-2000. Most important factors influencing children's BMI values were: obesity of both or at least one of the parents, being an only child, residence in small communities, and irregular breakfasts.
