Key Social Determinants to Narrow the Gap between Health-adjusted Life Expectancy and Life Expectancy in Megacities

ObjectiveImprovement in the quality of life is reflected in the narrowing of the gap between health-adjusted life expectancy (HALE) and life expectancy (LE). The effect of megacity expansion on narrowing the gap is rarely reported. This study aimed to disclose this potential relationship.MethodsAnnual life tables were constructed from identified death records and population counts from multiple administrative sources in Guangzhou, China, from 2010 to 2020. Joinpoint regression was used to evaluate the temporal trend. Generalized principal component analysis and multilevel models were applied to examine the county-level association between the gap and social determinants.ResultsAlthough LE and HALE in megacities are increasing steadily, their gap is widening. Socio-economic and health services are guaranteed to narrow this gap. Increasing personal wealth, a growing number of newborns and healthy immigrants, high urbanization, and healthy aging have helped in narrowing this gap.ConclusionIn megacities, parallel LE and HALE growth should be highly considered to narrow their gap. Multiple social determinants need to be integrated as a whole to formulate public health plans.

  目的  了解深圳市成年居民肥胖和向心性肥胖现状及其影响因素。  方法  于2018年在深圳市对常住居民开展慢性病及其危险因素调查,采用多阶段分层随机抽样抽取10 046名常住深圳市成年居民作为调查对象,分析肥胖与向心性肥胖的流行病学特征及影响因素。  结果  调查人群的肥胖率和向心性肥胖率分别为8.65%、38.04%,性别、年龄和吸烟均是影响肥胖率和向心性肥胖的主要因素(均有P＜0.05),男性、中老年人和吸烟是肥胖和向心性肥胖的危险因素(OR=1.411, 95% CI: 1.115~1.725, P=0.001; OR=1.155, 95% CI: 1.010~1.321, P=0.036),中强度职业性体力活动是向心性肥胖的保护因素(OR=0.856, 95% CI: 0.775~0.946, P=0.002)。  结论  虽然深圳市成年居民肥胖、向心性肥胖率略有降低,但仍有改善空间,相关部门应针对性的采取干预措施预防肥胖,尤其是向心性肥胖。     

我国40岁及以上吸烟人群烟草依赖严重程度及其影响因素分析

目的 了解我国≥40岁吸烟人群烟草依赖情况及其影响因素,为我国广泛开展戒烟干预提供科学数据。方法 本研究数据来源于2014-2015年中国居民慢性阻塞性肺疾病监测,覆盖31个省（自治区、直辖市）的125个监测点,以面对面询问调查的方式收集≥40岁居民吸烟和烟草依赖的相关变量。应用复杂抽样加权估计我国≥40岁现在吸烟和现在每日吸烟人群烟草依赖率及其95%CI并分析其影响因素。结果 纳入分析现在吸烟者22 380人,现在每日吸烟者19 999人。≥40岁现在吸烟人群的重度烟草依赖率为31.1%（29.3%~32.9%）,其中男性为32.0%（30.2%~33.9%）,高于女性17.6%（13.4%~21.7%）;乡村为32.7%（30.2%~35.2%）,高于城镇;40~59岁年龄组重度烟草依赖率较高,为33.3%（31.3%~35.2%）。≥40岁现在每日吸烟人群的重度烟草依赖率为35.0%（33.0%~37.0%）,男性为35.8%（33.8%~37.8%）,女性为22.0%（16.8%~27.2%）。在现在吸烟人群和每日吸烟人群中,文化程度越低,重度烟草依赖率越高;18岁以前开始吸烟者重度烟草依赖率明显高于18岁及以后开始吸烟者;有慢性呼吸道症状者的重度烟草依赖率明显高于无症状吸烟者;慢性呼吸系统疾病患者和非患者的重度烟草依赖率差异无统计学意义（P>0.05）;患有糖尿病、心脑血管疾病和高血压的吸烟者的重度烟草依赖率略低于非患者（P<0.05）。多因素logistic回归分析结果显示,男性、中部和东部地区、40~59岁年龄组、从事农林牧渔水利、生产运输和商业服务职业、文化程度低、18岁以前开始吸烟者患重度烟草依赖的风险高。结论 我国≥40岁吸烟人群的重度烟草依赖水平较高,戒烟干预服务客观需求巨大,应采取有效措施推动我国戒烟干预工作的开展。

目的 了解中国社区老年人脑认知相关生活方式的分布特征,并探讨其综合评分对早期认知功能下降的影响。方法 研究对象来自老年期重点疾病预防和干预项目。纳入2015年基线调查及2017年随访调查均完成认知功能状况评定,且基线未患痴呆的2 537名≥60岁的社区老年人。通过问卷调查收集其脑认知相关生活方式信息（体育锻炼、社会交往、脑力休闲活动、睡眠质量、吸烟状况与饮酒状况）并计算综合评分。通过多因素logistic回归模型分析脑认知相关生活方式综合评分与早期认知功能下降的关联。结果 2 537名社区老年人群中,评分5~6分者占28.7%,6项脑认知相关生活方式因子均健康者仅占4.8%。男性与女性的健康生活方式因子分布存在差异。多因素logistic回归模型结果显示,与评分0~3分组相比,评分4分和5~6分组早期认知功能下降的风险降低（OR=0.683,95%CI：0.457~1.019;OR=0.623,95%CI：0.398~0.976;趋势P=0.030）。在女性中,与评分0~3分组相比,评分4分和5~6分组的早期认知功能下降的风险降低（OR=0.491,95%CI：0.297~0.812;OR=0.556,95%CI：0.332~0.929;趋势P=0.024）。结论 脑认知相关综合健康生活方式与早期认知功能下降风险降低密切相关,在女性群体中尤为显著。     

山西营养与慢性病家庭队列人群体质指数与死亡率的关系

目的 分析山西营养与慢性病家庭队列人群BMI与总死亡率的关系。方法 以"2002年中国居民营养与健康状况调查"山西省调查人群为基线建立队列，于2015年12月至2016年3月对研究对象进行随访调查，对逝者进行死因回顾调查。2002年基线信息完整的≥ 18岁研究对象7 007人，随访到5 360人，随访率为76.5%。将研究对象按BMI分为8组，计算死亡率，以死亡率最低组作为参照，采用Cox比例风险回归模型估计全人群、分性别、年龄（≥ 60岁、<60岁）的各组死亡风险比（HR）及95% CI，模型调整基线年龄、性别、吸烟、饮酒、文化程度等因素，并进行敏感性分析。结果 共随访67 129人年，平均随访12.5年，死亡615人，队列总死亡率为916/10万人年。BMI为26.0~27.9 kg/m²组死亡率最低，以该组为参照组，多因素调整后，BMI<18.5、18.5~19.9、22.0~23.9和≥ 30.0 kg/m²组的死亡风险明显升高，调整HR值（95% CI）分别为1.90（1.26~2.86）、1.68（1.15~2.45）、1.49（1.08~2.06）和1.72（1.07~2.76）。对于≥ 60岁老年人，BMI<18.5 kg/m²组的死亡风险明显升高，调整HR值（95% CI）为1.94（1.20~3.15）。结论 BMI ≤ 19.9、22.0~23.9及≥ 30.0 kg/m²均会增加全因死亡风险。除关注肥胖外，低体重营养不良造成的老年人高死亡风险应特别引起重视。     

Interaction of poor sleep quality,family history of type 2 diabetes,and abdominal obesity on impaired fasting glucose: a population-based cross-sectional survey in China

This study aims to explore the interaction of sleep quality, family history of type 2 diabetes, and obesity in relation to impaired fasting glucose in a Chinese population. A representative population-based cross-sectional study was conducted, and 15,145 residents aged between 18 and 75 years were selected from 11 districts of Xuzhou City, Jiangsu Province. The Pittsburgh Sleep Quality Index was used to evaluate sleep conditions, with categories of good and poor. Impaired fasting glucose (IFG) was assessed by fasting blood glucose. Interaction of sleep quality, obesity, and family history of diabetes (FHD) on IFG was analyzed by logistic regression. Relative excess risk due to interaction (RERI) and the synergy index (SI) were applied to evaluate the additive interaction between the two factors. Either poor sleep or positive FHD was independently associated with an increased odds ratio (OR) for IFG. Those with both poor sleep and positive FHD had a significantly increased risk compared with those without poor sleep and FHD (OR 20.6, 95 % confidence interval (CI) 16.4–29.0, P?<?0.001). The corresponding RERI and SI was 14.6 (8.6–20.6) and 3.7 (1.4–5.1), respectively. Both abdominal obesity and FHD significantly increased the risk of being IFG. The synergistic effect of abdominal obesity and FHD on IFG was statistically significant (OR 40.1, 95 % CI 28.8–61.5). The results suggest that additive interactions exist between poor sleep quality, abdominal obesity, and family history of diabetes in relation to impaired fasting glucose.

Abdominal Obesity and Its Attribution to All-cause Mortality in the General Population with 14 Years Follow-up: Findings from Shanxi Cohort in China

Objective This study aimed to assess the association of waist circumference(WC) with all-cause mortality among Chinese adults.Methods The baseline data were from Shanxi Province of 2002 China Nutrition and Health Survey. The death investigation and follow-up visit were conducted from December 2015 to March 2016. The visits covered up to 5,360 of 7,007 participants, representing a response rate of 76.5%. The Cox regression model and floating absolute risk were used to estimate hazard ratio and 95% floating CI of death by gender and age groups(≥ 60 and 60 years old). Sensitivity analysis was performed by excluding current smokers; participants with stroke, hypertension, and diabetes; participants who accidentally died; and participants who died during the first 2 years of follow-up.Results This study followed 67,129 person-years for 12.5 years on average, including 615 deaths. The mortality density was 916 per 100,000 person-years. Low WC was associated with all-cause mortality among men. Multifactor-adjusted hazard ratios(HR) were 1.60(1.35–1.90) for WC 75.0 cm and 1.40(1.11–1.76) for WC ranging from 75.0 cm to 79.9 cm. Low WC( 70.0 cm and 70.0–74.9 cm) and high WC(≥ 95.0 cm) groups had a high risk of mortality among women. The adjusted HRs of death were 1.43(1.11–1.83), 1.39(1.05–1.84), and 1.91(1.13–3.22).Conclusion WC was an important predictor of death independent of body mass index(BMI). WC should be used as a simple rapid screening and predictive indicator of the risk of death.
