“…Children are assuming more responsibility for their own choices [9]. Additionally, in meta-analysis articles related to the prevalence of overweight and obesity in Asia and in the world, data about the OW/OB status of children at this age in Vietnam were not shown [10,11]. The present study aimed to determine the prevalence of OW/OB among secondary school children in Hanoi, Vietnam and to evaluate the factors that influence OW/OB in this population.…”

Background: The prevalence of overweight and obesity (OW/OB) has increased rapidly in Vietnam. This study aimed to elucidate the factors influencing OW/OB among secondary schoolchildren. Method: A survey was conducted in January 2014 in four randomly selected state schools in two Hanoi urban districts, and 821 students in grade six (11-12 years old) participated. Definitions of OW/OB followed the World Health Organization standard cutoffs. Results: Overall, 4.1% of children were underweight, 59.7% were normal weight, 17.1% were overweight, and 19.1% were obese. The odds of OW/OB were lowest among children whose parents had college/university degrees [father (aOR =0.65, 95% CI: 0.42-1.00); mother (aOR =0.63, 95% CI: 0.41-0.97)] compared with those whose parents had only a primary education. Children with an OW/OB family history had an increased risk of OW/OB. Other associated factors include parental OW/OB and birth weight (BW). The odds of OW/OB were highest among children with parents with OW/OB [father (aOR =2.022, 95% CI: 1.34-3.04); mother (aOR =2.83, 95% CI: 1.51-5.30)] compared with those with normal-weight parents. Children with both parents having OW/OB [both parents (aOR =6.59, 95% CI: 1.28-33.87) had the highest risk, followed by one parent (aOR =2.22, 95% CI: 1.50-3.27)] and then neither parent having OW/OB. Moreover, high-birth-weight children [BW ≥ 3500 g (aOR =1.52, 95% CI: 1.07-2.15)] had greater odds than did normal-birth-weight children. Children who slept 11 h per day [8-11 h (aOR =0.57, 95% CI: 0.40-0.81) or more (aOR =0.44, 95% CI: 0.22-0.87)] had lower OW/OB odds than those who slept 8 h or less. Children with specific positive lifestyle behaviours had lower risk of OW/OB than those who did not engage in positive lifestyle behaviours. The odds were lower among children who exercised for weight reduction (OR = 0.16, 95% CI: 0.11-0.23), lowered food intake (aOR = 0.12, 95% CI: 0.09-0.17), and added vegetables to their diet (aOR = 0.26, 95% CI: 0.19-0.35). Conclusion: The results suggest that parents and children with OW/OB parents or a high BW should be educated to prevent OW/OB at an early stage. Positive lifestyle behaviours should be adopted by the students.

“…Sex Sex affects the incidence of obesity. Mazidi, Banach, & Kengne (2018) found that the prevalence of obesity in male adolescents was higher than in female adolescents in Asian countries, stating the prevalence of obesity was 10.10% in male adolescents and 6.20% in female adolescents. This study is in line with that study, finding the incidence of obesity higher in male adolescents (54.20%) than in female adolescents (45.80%).…”

“…Hence, an awareness-raising preventive programme is needed for adolescents throughout Asia, especially given that obese adolescents tend to remain obese when they become adult. Previous studies have shown that to lose weight in adulthood is more difficult than at a younger age (Mazidi, Banach, & Kengne, 2018;Simmonds et al, 2015).…”

Background:The prevalence of adolescent obesity is increasing in Indonesia. Obesity can reduce the quality of life, especially as most obese adolescents remain obese after they become adult. In obese adolescents, the higher their IMT (intima-media thickness), the higher the risk of cardiovascular disease in adulthood. Purpose: The aim of this study is to analyse the correlation of demographic characteristics with BMI (body mass index) in adolescents with obesity. Methods: This study is a cross-sectional study on adolescents with obesity conducted in the Paediatric Nutrition and Metabolic Disease Clinic of Dr Soetomo General Hospital, Surabaya. The data on demographic characteristics, such as gender, number of siblings, paternal education, maternal education, and maternal occupation, were collected using the interview method. Data on anthropometry were collected to calculate BMI. Obesity is established if it is higher than the 95 th percentile, based on CDC percentile of BMI, according to age and sex. Data were analysed using multiple regression. Results: A total of 59 obese adolescents, between 13 and 16 years old, were involved. As many as 49.20% of respondents had one sibling. As many as 52.50% of respondents had a father with a high school education and 44.10% of respondents had mothers with a high school education; 61% of respondents had working mothers. There was no correlation between BMI and demographic characteristics (p> 0.05), except for number of siblings (p = 0.02). Conclusion: In this study, the number of siblings was correlated with BMI. A study with a greater number of obese adolescents and with adolescents who have normal nutritional status is needed to fully assess the influence of demographic characteristics on BMI in obese adolescents.

“…2 WHO has estimated that the majority of children with obesity live in developing countries, where the rates are increasing faster than in developed countries. 3 Monogenic obesity is a rare genetic disorder characterized by severe EOO with abnormal feeding behavior and endocrine disorders caused by defects in different genes of the leptin-melanocortin pathway that plays a key role in the hypothalamic control of food intake. 4 The most common single gene defect causing pediatric obesity is melanocortin-4 receptor defects comprising 5% to 6% of EOO.…”

Monogenic leptin deficiency in early childhood obesity

et al. 2019

View full text Add to dashboard Cite

Summary Background Early childhood obesity is a public health problem worldwide. It affects different aspects of physical and mental child's health. Identifying the etiologies, especially treatable and preventable causes, can direct health professionals toward proper management. Analysis of serum leptin levels and leptin gene mutations is a rapid and easy step toward the diagnosis of congenital leptin deficiency that is considered an important cause in early childhood obesity. Objectives The aim of this study was to diagnose monogenic leptin deficiency in Egyptian children presenting with early onset obesity (EOO). Methods The current cross‐sectional study included 80 children who developed obesity during the first year of life with BMI > 2 SD (for age and sex). The studied population was subjected to history taking, auxological assessment, serum leptin assay, and leptin gene sequencing. Results Ten cases had leptin deficiency (12.5%), while 18 cases showed elevated leptin levels (22.5%). Leptin gene variants in the coding region were identified in 30% of the leptin‐deficient group: two novel homozygous disease‐causing variants (c.104 T > G and c.34 delC) and another previously reported homozygous pathogenic variant (c.313C > T). Conclusion Leptin deficiency is considered a significant cause of monogenic obesity in Egyptian children with early‐onset obesity as the diagnosis of these patients would be a perfect target for recombinant leptin therapy.
