Analyzing the National Longitudinal Survey of Youth: A Comparison of Statistical Methods Presented: Minneapolis, MN, Joint Statistical Meetings, August 2005 Cohort(s): Children of the NLSY79, NLSY79 Publisher: American Statistical Association Keyword(s): Alcohol Use; Birthweight; Child Health; Cigarette Use (see Smoking); Modeling; Morbidity; Mortality; Obesity; Pre/post Natal Behavior; Weight Recent trends in obesity incidence and prevalence among America's youth have raised concern among the public health community. Although much ongoing research is aimed at addressing the concerns of obesity and its related morbidity and mortality, many questions remain unanswered. We used the National Longitudinal Survey of Youth NLSY79 Child and Youth data to investigate obesity incidence. These data contain not only factors of the children such as birth weight, gender and race, but also maternal factors such as mother's age at pregnancy, prenatal care, and alcohol and tobacco use during pregnancy. While these data are rich in many ways, they present interesting statistical challenges. For this data set, respondents were surveyed biennially. Censored and missing data in both outcome and predictor variables are some of the problems that must be taken into account when determining the influence of the individual and maternal factors on adolescent obesity incidence. We applied different statistical methods (parametric survival analysis, GLMM, and GEE) to these data and compared the results, describing the merits and drawbacks of each approach. |
