8 new entries make it into September’s top 10 most read articles. In first place is a study by Cynthia Graham and colleagues that reports findings from a cross-sectional survey of sexual attitudes and lifestyles in the UK. From data on 4839 men and 6669 women aged 16–74 years who reported ≥1 sexual partner in the past year, the authors found a number of different factors were associated with a lack of interest in sex in both genders, with women seeming to be more likely to lose interest than men overall. In second place was a systematic review and meta-analysis by Loubaba Mamluk and colleagues from the University of Bristol that assessed the evidence for the effects of low-to-moderate levels of maternal alcohol consumption in pregnancy on pregnancy and childhood outcomes. The authors found that high quality data on this topic was surprisingly limited. However, as there was some evidence to suggest that light drinking was associated with adverse pregnancy outcomes, abstention was recommended as the safest approach.

Finally, at number 4 this month is a systematic review by Siemieniuk et al. on the impact of various antiretroviral/antiviral regimens in pregnant women living with HIV or hepatitis B virus. The authors found that tenofovir/emtricitabine is likely to increase stillbirth/early neonatal death and early premature delivery compared with zidovudine/lamivudine. However, the authors caution that this finding primarily comes from a single study of moderate size.
