Association between self-reported snoring and hypertension among Chinese Han population aged 30-79 in Chongqing, China

BACKGROUND@#We aim to explore the association between self-reported snoring and hypertension among adults aged 30-79 in Chongqing, China.@*METHODS@#A total of 23,342 individuals aged 30-79 were included at baseline from August 2018 to January 2019, and the final sample size for the analysis was 22,423. Face-to-face interviews and physical examinations were conducted by trained investigators. Logistic regression was performed to study age-specific and gender-specific associations between snoring and hypertension.@*RESULTS@#Frequent snoring was associated with the risk of hypertension for each age and gender group, and the frequency of snoring was positively correlated with the risk for hypertension. For the three age groups (< 45, 45-59, ≥ 60), compared with the non-snoring group, those who snore often had a 64.5%, 53.3%, and 24.5% increased risk of hypertension (< 45: OR = 1.65, 95%CI 1.34-2.02; 45-59: OR = 1.53, 95%CI 1.37-1.72; ≥ 60: OR = 1.25, 95%CI 1.09-1.42), respectively. For men and women, those who snore often had a 46.8% and 97.2% increased risk of hypertension, respectively, than the non-snoring group (men: OR = 1.47, 95%CI 1.33-1.63; women: OR = 1.97, 95%CI 1.75-2.23).@*CONCLUSIONS@#People who snore frequently should pay close attention to their blood pressure levels in order to achieve early prevention of hypertension, particularly for snorers who are female and aged under 45; importance should be attached to their blood pressure control.

Analysis on probability of premature death and cause eliminated life expectancy of major non-communicable diseases in Chongqing Municipality, 2016 / 中华预防医学杂志

Objective@#To analyze the premature death probability and cause-eliminated life expectancy of cardiovascular disease, cancer, chronic respiratory disease and diabetes in Chongqing residents in 2016 so as to provide recommendation for non-communicable diseases (NCDs) prevention and control in Chongqing.@*Methods@#Death cases of Chongqing Municipality between January 1st and December 31st, 2016 were reported through death case registry system of national center for disease prevention and control. Death cases were sorted by international classification of disease (ICD-10). Mortality rate, standardized mortality rate, constituent ratio, premature death probability, life expectancy, and cause-eliminated life expectancy of four major NCDs were analyzed.@*Results@#A total of 218 004 death cases were reported in Chongqing, 2016, and the mortality rate was 731.73/100 000. Of them, a total of 179 637 death cases of the four major NCDs including cardiovascular disease, cancer, chronic respiratory disease and diabetes were reported, accounting for 82.40% of all death cases. The mortality rate and standardized mortality rate of four major NCDs was 602.95/100 000 and 455.82/100 000, respectively. The premature death probability of four major NCDs was 15.96%, and males (25.39%) had a higher premature death probability than females (10.78%). The premature death probability of cardiovascular disease, cancer, chronic respiratory disease, and diabetes were 6.01%, 8.32%, 2.05%, and 0.43%, respectively. Life expectancy would increase by 6.02, 3.19, 1.89, and 0.19 years, after eliminating cardiovascular disease, cancer, chronic respiratory disease and diabetes respectively.@*Conclusion@#The premature death probability of major NCDs was high in Chongqing, and males had a higher premature death probability than females did. Intervention and health management of the population should be conducted according to different gender-based risk factors to reduce the premature death probability.

Consideration and Suggestions on the Guarantee of the Supply of Essential Medicines / 中国药房

OBJECTIVE:To put forward suggestions for the guaranteeing of the supply of the essential medicines in China. METHODS:The problems occurred in the production,circulation and application of essential medicines as well as the policies issued in the medical reform including the assigned production,centralized purchasing,direct distribution and standard application were discussed.RESULTS & CONCLUSION:The essential medicines can be produced by selectively assigned production,and the continuity of the production of the essential medicines calls for efforts of multiple means.It is better for medicare agency to be responsible for centralized purchasing and the construction of the delivering and distributing system of medicines should be strengthened.The system of enforcement use and incentive measures should be established to ensure that the essentials medicines be used by clinicians.
