showed that high caloric dietary intake significantly decreased for the obese group (P < .001). Aerobic exercise activity also increased in both groups (P < .001) and prevalence of obesity declined from 19.3% to 16.8%. Thus, a long-term, participatory effort to promote healthy diets and physical exercise could be effective with primary school students and may establish habits that last to later life.

BackgroundThe prevalence of obesity has substantially increased in the past 3 decades in both developed and developing countries and may lead to an increase in high blood pressure (BP) at an early age. This study aimed to determine the prevalence of obesity and its association with blood pressure among primary school children in central Thailand.MethodsA cross-sectional study was conducted in two public schools in Bangkok in 2012. A total of 693 students (317 boys and 376 girls) aged 8–12 years participated voluntarily. Anthropometric measurements of weight, height, waist circumference (WC) and BP were collected. Fasting venous blood samples were obtained for biochemical analysis of fasting plasma glucose (FPG) and lipid parameters. Child nutritional status was defined by body mass index (BMI) for age based on the 2000 Center for Diseases Control and Prevention growth charts. The cutoff for abdominal obesity was WC at the 75 percentile or greater. Hypertension was defined according to the 2004 Pediatrics US blood pressure reference. Multinomial logistic regression was used to examine the relationship between high BP and obesity after controlling for other covariates.ResultsThe prevalence of obese children was 30.6% for boys and 12.8% for girls (mean prevalence 20.9%). Pre-hypertension (Pre-HT) was 5.7% and 2.7% for boys and girls and hypertension (HT) was 4.7% for boys and 3.2% for girls, respectively. Children with pre-HT and HT had significantly higher body weight, height, WC, BMI, SBP, DBP, TG, and TC/HDL-C levels but lower HDL-C levels than those children with normotension. After controlling for age, sex, glucose and lipid parameters, child obesity was significantly associated with pre-HT and HT (odds rations (ORs) = 9.00, 95% CI: 3.20-25.31 for pre-HT and ORs = 10.60, 95% CI: 3.75-30.00 for HT). So also was WC (abdominal obesity) when considered alone (ORs = 6.20, 95% CI: 2.60-14.81 for pre-HT and ORs = 13.73, 95% CI: 4.85-38.83 for HT) (p-value < 0.001).ConclusionsObesity among school children was positively associated with higher BP. Prevention of childhood obesity should be strengthened to prevent the risk of early high BP including cardiovascular risk factors.

Aim:  To evaluate the use of food experience, multimedia and role models for promoting fruit and vegetable consumption in kindergarten children. Methods:  A quasi‐experimental study was conducted. A Bangkok public primary school was randomly selected and one of the kindergarten levels was purposively chosen. Program implementation consisted of 11 activities over an eight‐week period from July to September, 2003. Data on demographic variables, and types and amounts of fruit and vegetables consumed and frequency of fruit and vegetables served were collected before and after the intervention. Program evaluation consisted of an analysis of the pre‐ and post‐test data. Results:  After the intervention, fruit and vegetable eating behaviour scores (median ± interquartile range) revealed significant changes from 3 ± 8 to 7 ± 8 for vegetables and 6 ± 8 to 9 ± 8 for fruit (P‐value < 0.001); the different types of consumed vegetables were increased from two to four (P‐value ≤ 0.001); and the fruit and vegetable intake was significantly increased from 53 g to 77 g and from 11 g to 23 g respectively (P‐value < 0.005). Conclusions:  Results of this pilot study were effective in increasing fruit and vegetable consumption in the kindergarten, however, longer‐term evaluation and assessment of the impact on the home environment are required. The inclusion of nutrition education and instruction on healthy eating habits in the course curriculum combined with social support from teachers and families may improve and sustain fruit and vegetable eating behaviours.

As a preliminary study, we determined the serum lipid profiles among primary school children from four Bangkok schools and identified the risk factors and their association with child lipid profiles. We conducted a cross-sectional study using fasting blood samples and food frequency questionnaires. Overall, there were 40% that had hypercholesterolemia with total cholesterol (TC) at > or = 200 mg/dl and high low density lipoprotein cholesterol (LDL-C) at > or = 130 mg/dl. Overall, 5.4% had high triglyceride (TG) levels at > or = 150 mg/dl. There was no association between lipid profiles and age, gender or nutritional status, except that higher TG levels were found among obese children than others (p < 0.001). The most popular high fat foods were fried chicken, sausages and cakes, in order of preference. Results from this study indicate that Bangkok public primary school children are facing a problem with hyperlipidemia. Build up discipline in healthy eating habits, healthy food choices and physical exercise should pave the way to healthy Thai kids and growing adults with better quality of life.
