This study investigated the actual status of constipation. In total, 978 female students in Korea participated. We identified the relationship among constipation and life style, clothing patterns, housing patterns, dietary habits, and dietary intake in a constipation symptom group and a normal group. The actual constipation rate based on the Rome II criteria was 27.0% (n = 264). Body weight (p < 0.05) and body mass index (p < 0.05) in the constipation group were significantly higher than those in the normal group. The incidence of functional bowel disease and irritable bowel syndrome in the constipation group were significantly higher than those in the normal group. The discomfort of wearing underwear was significantly higher in the constipation group than that in the normal group. The constipation group revealed a significantly higher rate of irregular dietary habits than those in the normal group. The dietary diversity score of the normal group was 4.22 (p < 0.05), which was significantly higher than that of constipation group (4.12). No significant difference in life style factors was observed. It is necessary for university female students to correct their dietary habits, maintain food intake of three times per day, and select diverse foods.

Objectives: The unsafe use of pesticides in agriculture represents a major hazard to human health. This study was conducted to investigate the association between pesticide exposure and health symptoms among chili farmers in northeast Thailand. Methods: This cross-sectional analytic study included 141 chili farmers in Sakon Nakhon Province, in northeast Thailand. Data regarding health symptoms were gathered using a self-report questionnaire. A medical technician tested blood cholinesterase activity using an erythrocyte method, and an occupational medicine specialist at Ramathibodi Hospital in Bangkok, Thailand reviewed the results. Associations between personal characteristics, pesticide exposure factors, and health symptoms were analyzed using multiple logistic regression. Results: Of the 141 chili farmers studied, 66.7% experienced pesticide poisoning, as indicated by below-normal cholinesterase levels. Fatigue was the most frequently reported symptom associated with pesticide exposure, affecting 37.6% of participants. This was followed by nausea and vomiting (31.9%), dizziness (14.9%), and dry throat (14.9%). Multivariate logistic regression analysis revealed that several factors were significantly associated with adverse symptoms: amount of work experience, volume of pesticides used, use of chemical pesticides, use of leaking containers during spraying, direct pesticide exposure while working, contact with pesticide-soaked clothing, consumption of food and drinks in the fields, and blood cholinesterase level indicating risk. Conclusions: This study suggests potential health risks for chili farmers stemming from exposure to and contamination by pesticides used in agricultural practices. To mitigate these risks, it is essential to supply personal protective equipment and to implement educational programs aimed at improving protective behaviors among farmers.
