摘要

本研究運用我國90年與94年國民健康訪問調查資料，分男女按體重分組估計體重控制對糖尿病衝擊中老年就業的緩和效果。為能考量糖尿病與體重控制為內生，使用帶工具變數三元Probit模型，工具變數包含糖尿病家族病史和糖尿病與體重控制二區域盛行率。比較二年度分析可知：90年因缺乏糖尿病家族病史且二區域盛行率變異不夠大,緩和效果較不明確；惟94年之分析則無此二項限制,過重以上（BMI ≥ 24）男性之緩和效果呈顯著為1.98%，其它各組之效果多偏小或不顯著。政策制定者估算體重控制成本效益時，宜將中老年過重以上男性之緩和效果納入考量。

This study examines whether weight control ameliorates the effect of diabetes on employment among middle-aged and older adults (aged 40 to 64) by gender and weight group. It analyzes two waves of the National Health Interview Survey of Taiwan (2001, 2005). Allowing for endogeneity of diabetes and weight control, it uses a trivariate probit model with instrumental variables, including the family history of diabetes, area prevalence rates of diabetes and weight control. Due to lack of family history of diabetes and insufficient variations in the two area prevalence rates, the findings from the 2001 wave are not totally according to expectation. However, the analysis of the 2005 data does not suffer similar constraints. The moderating effect for overweight or obese (defined as BMI ≥ 24) males is statistically significant, on the order of 1.98%. Most effects are either small or insignificant for other groups. Taking into account the moderating effect for overweight or obese, middle-aged and older males will enhance completeness of cost-benefit analysis in evaluating weight control policy.
