Work and family stress is associated with menstrual disorders but not with fibrocystic changes: cross-sectional findings in Chinese working women.

OBJECTIVES: To explore the separate and combined effects of work and family stress on menstrual disorders and fibrocystic changes in Chinese working women. METHODS: Data were obtained from a cross-sectional study of 1,642 female railway workers. The Effort-Reward Imbalance Questionnaire and Family Stress Scale were used to measure work stress and family stress, respectively; the menstrual and breast conditions were evaluated by gynecologic interview and a medical examination. Multivariate log-binomial regression was performed to analyze the associations. RESULTS: Menstrual disorders were found in 59.3% of female workers, and 54.8% had fibrocystic changes. The risk of menstrual disorders was significantly elevated with respect to work and family stress. The highest risk was found in the group with combined exposure to both work and family stress (RR with 95% CI 1.33 (1.18-1.49)). No significant association between stress and fibrocystic changes was observed. CONCLUSIONS: Menstrual disorders were associated with stress from work and family life, but not fibrocystic changes, in working women. Tailored intervention measures reducing the burden of stressful psychosocial work and family environment are needed to improve women's reproductive well-being.

[Association between job stress and blood lipids among university staff in Yunnan province].

OBJECTIVE: To observe the association between job stress (effort-reward imbalance model)and blood lipids among university staff in Yunnan province. METHODS: A cross-sectional survey was conducted among 1244 university staff in Yunnan province. The job stress was measured by the validated Chinese self-reported Effort-Reward Imbalance Questionnaire (ERI). Blood lipids were measured in all participated staff members. RESULTS: After adjustment for relevant confounding factors, it was found that the risk of increased serum triglyceride was 3.5 folds higher in male staffs with high extrinsic effort compared those with low extrinsic effort (OR = 3.45, 95%CI: 1.32 - 9.04) while the risk of increased serum low density lipoprotein-cholesterol was 2.9 folds higher in male staffs with high overcommitment compared those with low overcommitment (OR = 2.86, 95%CI: 1.03 - 7.96). The risk of elevated serum triglyceride increased in proportion to increasing job stress: 3.5 folds increase in male staffs with moderate job stress (OR = 3.43, 95%CI: 1.24 - 9.53) and 4 folds increase in male staffs with high job stress (OR = 4.16, 95%CI: 1.42 - 12.17) compared those with low job stress. However, there was no significant association between job stress and lipid profile in female staffs. CONCLUSION: Our results show that job stress (effort-reward imbalance) is positively associated with abnormal blood lipids in male university staffs.
