Objective: To compare the quality of life of pneumoconiosis patients between from rural migrant workers and from a state-owned enterprises in Zhaotong City Yunnan Province, and to explore the factors influencing quality of life of pneumoconiosis patients. Methods: In August 2017, 83 patients from rural migrant workers in Zhaotong City Yunnan Province and 126 pneumoconiosis patients from a state-owned coal mining enterprises were selected as target population. World Health Organization on Quality of Life Brief Scale (WHOQOL-BREF) and self-designed questionnaires were used to collect information from two groups. The demographic information, health status and quality of life of two groups were compared. The factors influencing quality of life were analyzed by multi-liner regression analyses. Results: Average annual household income of rural migrant workers group was lower than that of state-owned enterprises group, and the average annual household expenditure for health of rural migrant workers group was higher than that of state-owned enterprises group ( P <0.01) . Overall score of WHOQOL-BREF and scores for four domains including physiology, psychology, social relationship and environment of rural migrant workers group were lower than the scores of patients from state-owned enterprises group ( P <0.01) . The result of multi-liner regression analysis showed that average annual household income ( b =0.00015, 95% CI : 0.00010-0.00020) , being rural migrant workers ( b =-5.904, 95% CI : -8.436--3.372) , better action ability ( b =2.595, 95% CI : 0.706-4.483) and have complication ( b =-2.542, 95% CI : -4.698--0.387) were factors influencing overall score of WHOQOL-BREF of pneumoconiosis patients ( P <0.05) . Conclusion: The quality of life of pneumoconiosis patients from rural migrant workers is lower than that from state-owned enterprises. And the average annual household income, action ability and having complication or not are factors influencing the quality of life of pneumoconiosis patients.

Objective: To evaluate the association of sleep quality with hypertension in the elderly population aged 60 years and older of Jino nationality. Methods: In August 2015, a cross-sectional population-based survey was conducted to investigate the prevalence of hypertension in 805 subjects sampled by multistage stratified and cluster sampling from the elderly population of Jino nationality, the sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI, a poor sleep group was defined as having a global PSQI score>7, a good sleep group was with a score of 7 or less), and the multilevel Logistic regression model was applied to analyze the association of sleep quality with hypertension. Results: A total of 793 eligible participants were available for analysis. Overall, 118 participants (14.9%) were in the poor sleep group, and 675 participants (85.1%) were in the good sleep group. The prevalence of hypertension, prevalence of isolated systolic hypertension, average systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the poor sleep group were significantly high than those of the good sleep group[73.7%, 22.0%, (139.2±17.7) and (82.5±10.6) mmHg (1 mmHg=0.133 kPa) vs 33.0%, 9.0%, (131.2±15.0) and (78.5±8.9) mmHg, all P <0.05]. The results of covariate-adjusted multilevel Logistic regression model indicated that subjective sleep quality ( OR =2.64, 95% CI: 1.08-6.44), sleep latency ( OR =2.98, 95% CI: 1.52-5.86), sleep disturbance ( OR =2.93, 95% CI: 1.06-8.10), daytime dysfunction ( OR =3.86, 95% CI: 1.74-8.58) and poor sleep ( OR =3.98, 95% CI: 2.05-7.73) had the positive correlation with hypertension. Conclusions: The elderly population of Jino nationality with poor sleep have high SBP and DBP. There are positive associations of PSQI and its components with hypertension in the elderly population of Jino nationality.
