Socioeconomic and Environmental Determinants to Preterm Birth in Tibetan Women: An Analysis Based on the Hierarchically Conceptual Frame / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Preterm birth is a common cause of death in newborns and may result from many determinants, but evidence for the socioeconomic and environmental determinants of preterm birth in Tibetan women of childbearing age is limited. The aim of this study was to understand the current status of preterm birth in native Tibetan women and investigate the socioeconomic and environmental determinants.</p><p><b>METHODS</b>Data were drawn from a cohort study which was conducted from August 2006 to August 2012 in rural Lhasa, Tibet, China. A total of 1419 Tibetan pregnant women were followed from 20 weeks' gestation until delivery; the loss to follow-up rate was 4.69%. The incidence of preterm birth was estimated to show the status of preterm births in Tibet. Logistic regression models for longitudinal data were established, and odds ratios (ORs) together with 95% confidence intervals (CIs) were used to evaluate the association between the occurrence of preterm birth and 16 selected potential determinants based on the hierarchical conceptual frame.</p><p><b>RESULTS</b>The incidence of preterm birth was 4.58% (95% CI = 3.55-5.80%). After adjusting for health-related variables of the mothers and newborns, socioeconomic and environmental determinants associated with preterm birth included season (spring: OR = 0.28, 95% CI = 0.09-0.84; autumn: OR = 0.21, 95% CI = 0.06-0.69; and winter: OR = 0.31, 95% CI = 0.12-0.82) and calendar year of delivery (2010: OR = 5.03, 95% CI = 1.24-20.35; 2009: OR = 6.62, 95% CI = 1.75-25.10; and 2007-2008: OR = 5.93, 95% CI = 1.47-23.90).</p><p><b>CONCLUSIONS</b>The incidence of preterm birth among native Tibetan women was low and there was a decreasing trend in recent years; however, it is still essential to strengthen seasonal maternal care, extend the spacing between pregnancies, and reinforce adequate maternal nutrition.</p>

Cost-benefit analysis on the strategy of social health insurance regarding vaccination against influenza in Xi'an city / 中华流行病学杂志

<p><b>OBJECTIVE</b>To assess the economic implications of an annual vaccination strategy against influenza among people who were on a social-health program.</p><p><b>METHODS</b>A retrospective cohort study was conducted. 1900 persons who had received the influenza vaccine were served as vaccine group, while 1049 persons who did not receive the vaccine were served as controls. Cluster random sampling method was used. Both of these two groups came from Donfang Company in which there were 12,109 employers in total and all of them joined the social health insurance program. The survey was carried out when the influenza vaccine was given one year ago.</p><p><b>RESULTS</b>The rates of vaccine group and control group for respiratory system diseases and cardiovascular diseases who were hospitalized, were 0.51%, 2.47% and 1.64%, 5.62% which showed 68.90% and 56.05% decrease, when compared with the control group. The crude inpatient rate among vaccinees and control group after receiving the vaccination for three and four month were 0.62%, 0.80% and 0.28%, 1.00% respectively. The inpatient rate of oldest-age group decreased by 53.59%, compared with control group. The cost-benefit ratio generated by the use of influenza vaccine in reducing the hospitalization rate was 6.48:1 for Social Health Insurants in Xi'an city.</p><p><b>CONCLUSION</b>The Strategy to vaccinate the social-health-insured residents on influenza in Xi'an city had gained better economic benefits in reducing the hospitalization rate of respiratory system diseases and cardiovascular diseases for mild and old-aged persons.</p>
