The 2002 World Health Report documented that low fruit and vegetable intake are among the top ten risk factors contributing to attributable mortality and up to three million lives could be saved each year by adequate consumption of F&V across the globe, leading an examination of behavioral preferences of the individual and family social, environmental, and behavioral factors that constitute perceived barriers to fruit and vegetable consumption.
The study examines factors affecting the choice of eating fruits and vegetables by household members and calculates eating frequency probabilities of different population-origin associated with personal attributes and behavior.
Turkish Health Survey (THS) 2019 data from the Turkish Statistical Institute (TSI) national representative household panel is applied. Estimating a random-effect bivariate probit model of fruit and vegetable choice, we calculated marginal probabilities of choosing fruits and vegetables, the joint probability of choosing both, and conditional probabilities between choosing to eat either, detecting consumption synergy.
The role of uncontrolled variables in choosing to eat fruits and vegetable (F&V) differs between the decision of an average family and the decision of individual family members. The attitude is positive for an average family and contrasts with the negative attitude among some family members. Most individual and family attributes inversely affect fruit and vegetable choice across different groups, while a positive relationship exists between the likelihood of fruit and vegetable choice and attributes such as age, marital status, education, weight, having health insurance, income, and time and forms of physical activity.
Instead of a general policy for the implementation of a healthy and balanced nutrition program to improve fruit and vegetable eating frequency, it appears more effective to adopt programs with distinct characteristics that segregate society into different cohorts. We suggest appropriate policies and offer suitable approaches to reach targeted groups.
2002 年世界卫生报告指出，水果和蔬菜摄入量低是导致可归因死亡率的十大风险因素之一，全球范围内通过充分摄入水果和蔬菜，每年最多可挽救 300 万人的生命，这促使人们研究个人行为偏好以及构成水果和蔬菜消费障碍的家庭社会、环境和行为因素。
本研究考察了影响家庭成员选择食用水果和蔬菜的因素，并计算了与个人属性和行为相关的不同人群来源的食用频率概率。
应用土耳其统计局（TSI）全国代表性家庭面板的 2019 年土耳其健康调查（THS）数据。通过估计水果和蔬菜选择的随机效应双变量概率模型，我们计算了选择食用水果和蔬菜的边际概率、选择两者的联合概率，以及在选择食用其中之一的条件概率，检测消费协同作用。
在选择食用水果和蔬菜（F&V）方面，未控制变量对平均家庭和个别家庭成员决策的作用不同。平均家庭的态度是积极的，而一些家庭成员的态度则是消极的。大多数个人和家庭属性在不同群体中对水果和蔬菜的选择产生负面影响，而水果和蔬菜选择的可能性与年龄、婚姻状况、教育程度、体重、是否有健康保险、收入以及时间和形式的体育活动等属性之间存在正相关关系。
对于实施健康均衡营养计划以提高水果和蔬菜食用频率的一般政策而言，采用具有不同特征的计划似乎更为有效，这些计划将社会分隔为不同的群体。我们建议采取适当的政策，并提供合适的方法来针对目标群体。
