A Probit Latent Variable Model of Nutrition Information and Dietary Fiber Intake
利用美国住户膳食计划者的调查数据，估计纤维信息对膳食纤维摄入的影响，发现收入、年龄、教育等因素通过信息渠道间接影响摄入。
Abstract Nutrition information and intake data for a sample of U.S. household meal planners are used to estimate the effects of fiber‐specific information on dietary fiber intake. The information variables are measured using survey questions on fiber content of foods, attitude toward consuming fiber‐rich foods, and awareness of fiber‐health links. The evidence confirms the influence of nutrition information on fiber intake. Household income, meal planner age, smoking status, vegetarian status, race, and ethnicity are major determinants of both information and intake. Education exerts a sizable intake effect by enhancing the information level. Direct and indirect effects of exogenous variables are reported.
