AB  - BACKGROUND: Family-based child obesity prevention and control strategy has not 
      yet established in many countries or regions, including China, thus what it needs 
      to do now is to continuously develop and improve the strategies. The purpose of 
      this study were to describe a wider spectrum of risk factors of obesity among 
      preschool children and add to the mounting evidence for further improving 
      suggested intervention measures in future family-based programs. METHODS: Data 
      was collected as part of a series of national epidemiological surveys in 
      childhood conducted in 9 Chinese cities. A population-based, 1:1 matched 
      case-control design was employed to examine risk factors of obesity by means of 
      conditional logistic regression. Obesity was defined as the International Obesity 
      Task Force (IOTF) BMI-for-age cut offs. Eligible subjects were 1234 boys and 610 
      girls aged 3-7 years in 1996 and 2290 boys and 1008 girls in 2006, including 
      obese and non-obese. RESULTS: High birth weight, gestational hypertension and 
      parents' BMI were closely associated with childhood obesity. Breast feeding in 
      the first 4 months was a protective factor in univariate model in 2006 
      (OR = 0.834, P = 0.0234), but the association was not seen in multivariate. 
      Appetite, eating speed, daily time and intensity for outdoor activities, night 
      sleep time, and time for TV viewing were identified statistically by multivariate 
      model. Those children brought up in extended family or mainly raised by their 
      grandparents or lived in high income or low education families might have an 
      increased risk of becoming obese. Parents' attitudes on weight control of their 
      children significantly differed between obese and non-obese groups. DISCUSSION: A 
      wider spectrum of risk factors and an empirical aggregation of family-related 
      risk factors are discussed to further improve future family-based child obesity 
      prevention and control strategies. Most of the risk factors identified by this 
      study presented ranked or quantitative characteristics which might be transformed 
      from unhealthy threshold to healthy range by behavior modification. Some 
      variables are likely to interact each other, such as appetite and eating speed, 
      or outdoor activity and TV viewing, or BMI and income, but which needs to be 
      further explored in future surveys. CONCLUSIONS: The family-related risk factors 
      were summarized from our identified risk factors of obesity among preschool 
      children which strongly supported the further development of family-based 
      programs in preschool period.
