Coverage and determinants of infant postnatal care in Nigeria:A population-based cross-sectional study

Importance:In 2019,Nigeria had the largest number of under-5 child deaths globally and many of these deaths occurred within the first week of life.The World Health Organization recommends infant postnatal care(PNC)attendance to support newborn survival;however,utilization of PNC is known to be low in many contexts.Objective:This study examined coverage and individual-level determinants of infant PNC attendance in Nigeria.Methods:Nigeria Demographic Health Survey(NDHS)2018 data were used to evaluate infant PNC coverage and determinants.Infant PNC was defined as receipt of care within 2 days of birth.Children delivered up to 2 years before the 2018 NDHS were included.We examined predictors of infant PNC with modified Poisson regression models to estimate relative risks(RRs).Results:The national coverage of infant PNC was 37.3%(95%confidence interval[CI]:35.8%–38.7%).Significant heterogeneity in PNC attendance existed at state and regional levels.Facility delivery was strongly associated with the uptake of PNC(RR:6.07;95%CI:5.60–6.58).Greater maternal education,maternal employment,urban residence,female head of household,and greater wealth were also associated with an increased likelihood of PNC visits.Interpretation:The uptake of infant PNC is low and interventions are urgently needed to promote equity in access and increase demand for PNC in Nigeria.

HIV infection among new synthetic drug abusers： a pilot study in Beijing

Background Following the increased human immunodeficiency virus （HIV） notification （infection） rates via sexual transmission and increased abuse of new synthetic drugs instead of heroin in China, a study on HIV infections and risk factors among synthetic drugs and heroin users in Beijing was conducted to provide a cue for further development of targets and strategies of HIV/AIDS control and prevention for different drug populations. Methods A total of 428 subjects including 224 heroin users and 204 new synthetic drug users was recruited from communities in Beijing by convenience sampling. A X2 test was used to compare HIV and syphilis infections between the two subpopulations. Logistic regression models were used to evaluate factors related to HIV, syphilis infections and abuse of synthetic drugs. Results Unbalanced distributions of demographics were detected between the two subpopulations. Compared with heroin users, most users of synthetic drugs were migrants, single and of younger age （age 〈30 years）. Ten HIV infections and twenty-four syphilis infections were confirmed among 428 subjects. No significant difference in HIV infection was found between the two subpopulations （crude odds ratio （OR） =0.46, 95% confidence interval （CI）： 0.07-15.80 and adjusted odds ratio （AOR） =1.26, 95% Ch 0.09-18.28） while four times as many syphilis infections were identified among users of synthetics drugs （AOR=3.92, 95% CI： 1.06-14.56）. HIV and syphilis infections appeared to work synergistically.The migrants who were of Han ethnicity, single and who had stayed in Beijing for more than six months were more likely to abuse synthetics drugs. Conclusions The new synthetic drug users and heroin users are different subpopulations. We optimistically speculate that HIV has not yet been introduced into the former in Beijing, but considering higher syphilis infections in synthetic drug users and the role of syphilis in HIV infection, synthetic drug users, as a possible and important driver of the HIV/AIDS epidemic in Beijing, should be paid more attention in HIV prevention and control strategies.
