Abstract:
OBJECTIVE:To explore the factors associated with the sex disparity showing a greater prevalence of obesity/overweight in boys compared with girls in Chinese school children. METHODS:Sampled students and their parents were asked to complete a questionnaire. Perceptions of weight status by the parents, grandparents and children themselves were collected. A logistic regression analysis was used. RESULTS:The sampled students included 327 obese/overweight students and 1078 students with normal body mass index (BMI). The crude OR of obesity/overweight for boys compared with girls was 1.57 (95% CI 1.22 to 2.01). The increased risk of childhood obesity/overweight for boys remained after adjustment for prenatal and infant factors, daily habits and family situation, but disappeared after adjustment for perception of weight status (OR 1.27 [95% CI 0.93 to 1.67]). There were differences in underestimation of children's weight status between boys and girls by their parents and grandparents (OR 1.33 [95% CI 1.08 to 1.64] and OR 1.42 [95% CI 1.15 to 1.75], respectively). CONCLUSIONS:Misconceptions about a child's weight status were prevalent among parents and grandparents, and boys' weight status was more frequently underestimated than girls. The disparity of underestimating weight according to sex may partially contribute to the difference in the prevalence of obesity/overweight between boys and girls among Chinese school children. OBJECTIF:Explorer les facteurs associés à l’écart entre les sexes qui démontrent une plus grande prévalence d’obésité et d’embonpoint chez les écoliers que chez les écolières en Chine. MÉTHODOLOGIE:Les chercheurs ont invité un échantillon d’élèves et leurs parents à remplir un questionnaire. Ils ont colligé les perceptions des parents, des grands-parents et des enfants. Ils ont utilisé une analyse de régression logistique. RÉSULTATS:L’échantillon se composait de 327 élèves obèses ou faisant de l’embonpoint et de 1 078 élèves à l’indice de masse corporelle (IMC) normal. Par rapport aux filles, le rapport de cotes brut d’obésité et d’embonpoint pour les garçons était de 1,57 (95 % IC 1,22 à 2,01). Le risque accru d’obésité ou d’embonpoint juvénile des garçons était maintenu après rajustement compte tenu de facteurs liés à la prénatalité et au nourrisson, aux habitudes quotidiennes et à la situation familiale, mais disparaissait après rajustement compte tenu de la perception du poids (RC 1,27 [95 % IC 0,93 à 1,67]). Les parents et les grands-parents sous-estimaient le poids des garçons et des filles de manière différente (RC 1,33 [95 % IC 1,08 à 1,64] et RR 1,42 [95 % IC 1,15 à 1,75], respectivement). CONCLUSIONS:L’évaluation erronée du poids d’un enfant est prévalente chez les parents et les grands-parents, le poids des garçons étant plus sous-estimé que celui des filles. L’écart de sous-estimation du poids entre les sexes peut contribuer à la différence de prévalence d’embonpoint ou d’obésité chez les écoliers et écolières en Chine.
