             This study aimed to study eating behaviors and factors predicting eating behaviors among pregnant women working in industrial factories. Samples were 210 pregnant women who visited antenatal clinics at social security center, Queen Savang Vadhana Memorial hospital. Data were collected by questionnaires including demographic data, eating behaviors, perceived nutritional benefit, perceived nutritional barrier, perceived nutritional self-efficacy, social support, and healthy food source in industrial factories. The content validity index of all questionnaires were 1.00 and the Cronbach’s alpha of questionnaires were .82, .84, .85, .90, .86 and .81, respectively. Data were analyzed using descriptive statistics and stepwise multiple regression.

        The result found that average of eating behaviors was 37.33 (SD = 4.52). The significant factors which predicted eating behaviors included perceived nutritional self-efficacy (β = .286, p < .001), perceived nutritional barrier (β = -.249, p < .001), healthy food sources in industrial factories (β = .142, p = .023) and perceived nutritional benefit (β = .142, p = .031). The percentage of total variance explained by these factors among pregnant women working in industrial factories was 22.3%. The results of this study could develop the guideline for promoting the healthy eating behaviors among pregnant women working in industrial factories.
