Behavioral intervention reduces unhealthy eating behaviors in preschool children via a behavior card approach.

Many eating behaviors form in childhood, and some unhealthy behaviors may persist into adulthood and have potential impacts on people's health. This study evaluated the effectiveness of behavioral intervention in reducing consumption of Western fast food, sweetened beverages, fried food in preschool children, and changing parents' rewarding behaviors that encourage the consumption of the unhealthy foods. The research was a cluster randomized trial of seven kindergartens, involving 1138 children aged 3-6 years and their parents in Beijing, China.

Feeding methods, sleep arrangement, and infant sleep patterns: a Chinese population-based study.

Background: Findings from prior research into the effect of feeding methods on infant sleep are inconsistent. The objectives of this study were to examine infants' sleep patterns by feeding methods and sleep arrangement from birth to eight months old.

Methods: This longitudinal cohort study enrolled 524 pregnant women at 34-41 weeks of gestation and their infants after delivery in 2006 and followed up until eight months postpartum.

[Waist circumference reference values for screening cardiovascular risk factors in Chinese children and adolescents aged 7 - 18 years].

Objective: To explore the optimal threshold values of waist circumference (WC) in detecting the risk on cardiovascular (CV) among the Chinese children and adolescents.

Methods: Association of WC and CV risk factors were studied among 65 898 children and adolescents aged 7 - 18 years whose data were pooled from nine studies carried out in China. Receive-operating characteristic analysis (ROC) and logistic regression were employed to derive optimal age- and sex-specific waist circumference references for predicting the CV risk factors.

Waist circumference reference values for screening cardiovascular risk factors in Chinese children and adolescents.

Objectives: To explore the optimal threshold values of waist circumference (WC) for detecting cardiovascular (CV) risk factors among Chinese children and adolescents.

Methods: Association of WC with CV risk factors was studied among 65,898 children aged 7-18 years whose data were pooled from nine previous studies in China. CV risk factors in this study included hypertension (blood pressure above 95 percentile levels), dyslipidemia (with one or more of the following three indexes: TG > or = 1.

[Development of sleep/wake patterns in infants during the first 12 months of life].

Objective: This was a nationwide study of sleep circadian in term infants. The aim was to understand the development characteristics of infants' sleep/wake patterns longitudinally in their own home environments over the first 12 months of life.

Method: Totally 524 healthy term infants from 9 urban districts took part in this project Their sleep/wake patterns over 24 h were recorded using parental sleep diaries, from the 2nd day to 12 months old.

Vitamin A deficiency and child feeding in Beijing and Guizhou, China.

Background: Vitamin A deficiency (VAD) is one of the three major micronutrient deficiencies in the world. In order to investigate the status of VAD and child feeding in China, we conducted the survey in Beijing city and Guizhou province.

Methods: We included a high socioeconomic area (Beijing) and a low socioeconomic area (Guizhou province) in China in our study.

[Study on prevalence and risk factors of sleep disorder among Chinese children aged 0 to 23 months in city].

Objective: To investigate the prevalence and main influences on sleep disorder among Chinese children aged 0 to 23 months, as to providing scientific interventions for infant sleep disorder.

Methods: All 7601 children under two years old were selected by stratifying samples from twelve cities in China. The objects' parents were surveyed with questionnaire.

[Family risk factors of overweight and obesity in preschool children].

Objective: To explore family risk factors of overweight and obesity focusing on parental characteristics, feeding practice and lifestyle.

Methods: Five kindergartens were selected randomly from two of all the six urban districts in Beijing. The body height and weight of all the children in the 5 kindergartens were measured in light clothing and without shoes.
