Abstract
The purpose of this cross-sectional descriptive research was to study the knowledge and safe consumption behavior of vegetables and fruit from pesticides and serum cholinesterase levels in pregnant women in Thasala district, Nakhon Si Thammarat province. The sample was 156 pregnant women. The data was collected during April – June 2019 by using the personal questionnaire, the knowledge of fruit and vegetable consumption questionnaire based on the content validity index (CVI) wich was 0.85 and the reliability index KR-20 was 0.98. The behavior of fruit and vegetable consumption questionnaire based on the content validity index (CVI) of 0.85, the Cronbach's alpha coefficient was 0.75, the cholinesterase reactive paper sensitivity was 77.04%, the specificity was 90.01% and the positive predicted value was 90.38%. Analysis of the personal data and behavior and the knowledge of fruit and vegetable consumption were done by percentage, average and standard deviation. The correlation was analyzed by using Chi-square test.
The research result showed that the averages of sample age were 28.48 years old (SD = 6.38), 64.10% graduated from secondary school. The averages of gestational age were 19.17 weeks (SD = 10.86). 40.38% were pregnant in the first trimester who had proper consumption quantity at 18.59% and 19.87% successively. Most of them were knowledgeable about the consumption of vegetables and fruit safely at 58.98%, followed by high level at 40.38%. The behavior of consumption of vegetables and fruits is safe at a high level of 87.73%. Knowledge correlated with safe vegetable and fruit consumption behavior (p < .01) but knowledge and behavior did not correlate with serum choline levels.
