title: [An Analysis on the Association between Lipid Metabolism and Low Birth Body Mass and Relative Factors among Rural and Urban Adolescents].
abstract: OBJECTIVE
  To analyze the status of lipid metabolism and the relationship between low birth body mass and lipid metabolism disorders in adolescents with different economic and cultural backgrounds.
  
  
  METHODS
  Totally 1700 adolescents from urban and rural areas aged 12-18 years were selected in 2013. The lipid profiles were determined, and a questionnaire-based survey was conducted.
  
  
  RESULTS
  Among normal birth body mass adolescents, girls obtained a high density lipoprotein in both urban and rural areas, low density lipoprotein cholesterol level was higher for city girls, rural boys and urban girls obtained higher total cholesterol level, the differences all reached statistical significance. While among the low birth body mass adolescents, higher level of total cholesterol for urban boys was detected, with statistically significance. When compared between rural and urban areas, high density lipoprotein cholesterol level for urban adolescents was lower in normal birth body mass adolescents, while total cholesterol level for urban adolescents was higher, both with statistically significance. While the comparison between different birth body mass adolescents suggested that the normal birth body mass adolescents obtained a higher high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride and total cholesterol level. When analyze the influenced factors of disorder of lipid metabolism, the Results suggest that low birth body mass, maternal pregnancy body mass increasing, lipid homeostasis family history, absence of breakfast, unhealthy snack habit, abnormal of systolic blood pressure and pulse pressure increasing were related to the occurrence of dyslipidemia.
  
  
  CONCLUSIONS
  Low birth body mass is related with lipid metabolism in early puberty. Low birth body mass, family history of abnormal lipid metabolism, and poor diet habits can increase the risk of abnormal lipid metabolism in puberty.
