Cardiovascular disease risk factors among school children of Bangladesh: a cross-sectional study.

ABSTRACT: OBJECTIVE:Primarily, we assessed the distribution of cardiovascular disease (CVD) risk factors among school children living in urban and rural areas of Bangladesh. In addition to this, we sought the association between place of residence and modifiable CVD risk factors among them. DESIGN, SETTING AND PARTICIPANTS:This cross-sectional study was conducted among 854 school children (aged 12-18 years) of Bangladesh. Ten public high schools (five from Dhaka and five from Sirajgonj district) were selected randomly and subjects from those were recruited conveniently. To link the family milieu of CVD risk factors, a parent of each children was also interviewed. PRIMARY AND SECONDARY OUTCOME MEASURES:Distribution of CVD risk factors was measured using descriptive statistics as appropriate. Again, a saturated model of binary logistic regression was used to seek the association between place of residence and modifiable CVD risk factors. RESULTS:Mean age of the school children was 14.6±1.1 years and more than half (57.6%) were boys. Overall, 4.4% were currently smoker (urban-3.5%, rural-5.2%) with a strong family history of smoking (42.2%). Similar proportion of school children were identified as overweight (total 9.8%, urban 14.7%, rural 5%) and obese (total 9.8%, urban 16.8%, rural 2.8%) with notable urban-rural difference. More than three-fourth (80%) of them were physically inactive with no urban-rural variation. Only 2.4% consumed recommended fruits and/ or vegetables (urban-3.1%, rural-1.7%). In the adjusted model, place of residence had higher odds for having several modifiable CVD risk factors: current smoking (OR: 1.807, CI 0.872 to 3.744), inadequate fruits and vegetables intake (OR: 1.094, CI 0.631 to 1.895), physical inactivity (OR: 1.082, CI 0.751 to 1.558), overweight (OR: 3.812, CI 2.245 to 6.470) and obesity (OR: 7.449, CI 3.947 to 14.057). CONCLUSIONS:Both urban and rural school children of Bangladesh had poor CVD risk factors profile that demands further nation-wide large scale study to clarify the current findings more precisely.

Project description:BackgroundFor over 20?years, Madagascar has been challenged by continued high prevalence of stunting, underweight and wasting among children under 5 years of age. Yet, nutritional status of post-under-five age group has never been assessed in the country, despite its importance in relation not only to physical health but also to cognitive capacity and educational achievements of children. This study aims to estimate prevalence of malnutrition among schoolchildren aged 5-14?years in Madagascar. It further attempts to identify the possible risk factors for their malnutrition. This is the first study that estimates prevalence of malnutrition among school-aged children in Madagascar.MethodsA cross-sectional household survey was conducted in Antananarivo-Avaradrano district, Analamanga region, Madagascar. The study targeted 393 first and second graders 5-14?years of age enrolled at 10 primary schools, where school-feeding was implemented. Data were collected from anthropometric measurements, their subsequent household structured interviews and observations. Bivariate (Chi-square test or Mann-Whitney's U test) and multivariable (logistic regression) analyses were performed, to identify the possible risk factors associated with malnutrition.ResultsThe overall prevalence rates of stunting, underweight and thinness were 34.9%, 36.9% and 11.2%, respectively. Nineteen children (4.8%) suffered from all the three forms of undernutrition. Older schoolchildren had a significantly greater likelihood of being stunted, underweight and thin. The greater number of members a household had, the higher likelihood of being stunted and thin its schoolchild had. Children having lower Household Dietary Diversity Score were more likely to be underweight. Yet, 'Had lunch at school yesterday' was associated neither with being stunted nor with being underweight and thin. This implies room for improvement of the current school feeding program.ConclusionsPrevalence rates of stunting and underweight among 393 children examined were as high as the national averages among children under 5 years of age. Adequate food availability and dietary diversity over a sufficient period (incl. 5-14?years of age) are necessary for increasing likelihood of catch-up in height-for-age and weight-for-age, which are expectable during adolescence. To supplement inadequate household dietary diversity practices, school-feeding program may need to use more animal-protein ingredients.

Project description:ObjectiveEarly detection of cardiovascular disease (CVD) risk factors, such as obesity, is crucial to prevent adverse long-term effects on individuals' health. Therefore, the aims were: (1) to explore the robustness of neck circumference (NC) as a predictor of CVD and examine its association with numerous anthropometric and body composition indices and (2) to release sex and age-specific NC cut-off values to classify youths as overweight/obese.DesignCross-sectional study.Setting23 primary schools and 17 secondary schools from Spain.Participants2198 students (1060 girls), grades 1-4 and 7-10.MeasuresPubertal development, anthropometric and body composition indices, systolic and diastolic blood pressure (SBP and DBP, respectively), cardiorespiratory fitness, blood sampling triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), glucose and inflammatory markers. Homoeostasis model assessment (HOMA-IR) and cluster of CVD risk factors were calculated.ResultsNC was negatively associated with maximum oxygen consumption (R2=0.231, P<0.001 for boys; R2=0.018, P<0.001 for girls) and adiponectin (R2=0.049, P<0.001 for boys; R2=0.036, P<0.001 for girls); and positively associated with SBP, DBP, TC/HDL-c, TG, HOMA, complement factors C-3 and C-4, leptin and clustered CVD risk factor in both sexes (R2 from 0.035 to 0.353, P<0.01 for boys; R2 from 0.024 to 0.215, P<0.001 for girls). Moreover, NC was positively associated with serum C reactive protein and LDL-c only in boys (R2 from 0.013 to 0.055, P<0.05).ConclusionNC is a simple, low-cost and practical screening tool of excess of upper body obesity and CVD risk factors in children and adolescents. Paediatricians can easily use it as a screening tool for overweight/obesity in children and adolescents. For this purpose, sex and age-specific thresholds to classify children and adolescents as normal weight or overweight/obese are provided.

Project description:Objective and designWe explored the cross-sectional and longitudinal associations of thyroid function within the normal range with cardiovascular disease (CVD) risk factors and adiposity measures.Patients and measurementsA total of 3483 (50·4% women) participants for the cross-sectional CVD study and 1630 (41·2% women) participants for the cross-sectional body composition substudy were drawn from the Framingham Third Generation Exam 1; 2912 participants (50·1% women) for the longitudinal CVD study and 713 participants (35·9% women) for the longitudinal body composition substudy were drawn from the Framingham Third Generation Exams 1-2. Thyroid function was assessed by thyrotropin [thyroid-stimulating hormone (TSH)] and free thyroxine (fT4) concentrations within the reference range at Exam 1. The associations between thyroid function and CVD risk factors were modelled via multivariable-adjusted regression models. Multivariable adjustment included age, sex, current smoking, postmenopausal status and BMI.ResultsCross-sectionally, higher TSH concentration was associated with increased odds of hypertriglyceridaemia [odds ratio (OR)=1·10], and higher BMI (β = 0·19 kg/m2 ), total cholesterol (β = 0·05 mmol/l), triglycerides (β = 0·0006 mmol/l) and subcutaneous adipose tissue (SAT) volume (β = 38·8 cm3 ) (all P < 0·05). Cross-sectionally, fT4 was inversely associated with metabolic and adiposity-related CVD risk factors, including obesity (OR = 1·17), hypertriglyceridaemia (OR = 1·09), BMI (β = 0·42 kg/m2 ), total cholesterol (β = 0·05 mmol/l), triglycerides (β = 0·0002 mmol/l), visceral adipose tissue (VAT) volume (β = -20·7 cm3 ) and attenuation (0·17 HU) and VAT/SAT ratio (β = -0·01) (all P < 0·05). However, during 6·1 years of follow-up, baseline TSH and fT4 levels were not longitudinally associated with CVD risk factors and adiposity measures.ConclusionsThyroid function within the normal range is cross-sectionally, but not longitudinally, associated with CVD risk factors and adiposity measures.
