Prenatal factors associated with high BMI status of infants and toddlers / 中华儿科杂志

<p><b>OBJECTIVE</b>To explore prenatal related factors of high BMI status in children at 1 and 2 years of age.</p><p><b>METHOD</b>A total of 2 220 newborns from Shenyang, Wuhan and Guangzhou were recruited in this birth cohort, thereafter they were followed up to two years of age.Self-administered questionnaires were used to collect such variables as social-demographic characteristics and feeding practice, etc. The anthropometric measures of children were collected by trained health staff. The data were subjected to multiple logistic regression analysis to determine the related factors for high BMI among infants and toddlers.</p><p><b>RESULT</b>The number of children with high BMI status were 550 (32.80%) at one year of age and 309 (26.23%) at two, respectively. The number of boys with high BMI status were 178 and girls 309 at age two years. The prevalence of high BMI status among boys (29.1%) at age two was significantly higher than that of girls (23.1%) (χ² = 5.52, P = 0.02). Logistic regression analysis showed that after the adjustment for sex, parental educational level, family economic status and other confounding factors, maternal passive smoking during pregnancy [OR:aged one:1.38 (1.05-1.82);aged two:1.48 (1.05-2.09)], maternal pre-pregnancy overweight and obesity [aged one:1.29 (1.05-1.58); aged two:1.35 (1.04-1.76)], paternal overweight and obesity [aged one:1.50 (1.21-1.87); aged two:1.47 (1.11-1.95)] and birth weight [aged one:1.53 (1.05-1.82); aged two:1.87 (1.33-2.63)]were identified to be associated with high BMI status in children.</p><p><b>CONCLUSION</b>Maternal passive smoking during pregnancy, paternal and maternal (pre-pregnancy) overweight or obesity and high birth weight are found to be important related factors for high BMI status in young children. Childhood overweight/obesity prevention should be considered starting as early as before pregnancy.</p>

The relationship between behavior and social ability development of urban 2～3 years old toddlers / 中华行为医学与脑科学杂志

Objective To explore the relationship between the behavior and social ability development of Chinese urban 2 ～ 3 years old toddlers. Methods The number of 2601 toddlers aged 2～3 years old were involved by random cluster sampling under the cross-sectional study from 14 large-media cities in China and surveyed by Child Behavior Checklist(CBCL 2/3) and Chinese Toddler Social and Emotional Assessment CTSEA) Questionnaire. The multiple stepwise regression analysis was used to analyze the surveyed results. Results In 2601 toddlers,there were 194 toddlers detected positive about the behavior, the rate was 7. 5% , including boys 107 (4.11%) and girls 87 (3. 34%),and there was gender differences in positive rates of the behavior(t = 2.36,P< 0.05). Otherwise,268 toddlers were detected positive about social-emotional ability,the rate was 10.3% .including boys 139 (5.34%) and girls 129 (4.96%), there also was gender differences in suspected positive rates of social-emotional ability(t = 3.60, P<0.01). The multiple stepwise regression analysis results indicated that attacks, damage,depression,withdrawal were correspond correlated with compliance,empathy,prosocial-peer-relations and imitation. Conclusion Cultivating good habits would promote the development of children' s social ability.
