Does higher early neonatal mortality in boys reverse over the neonatal period? A pooled analysis from three trials of Nepal.

ABSTRACT:

Objectives

Neonatal mortality is generally 20% higher in boys than girls due to biological phenomena. Only a few studies have examined more finely categorised age patterns of neonatal mortality by sex, especially in the first few days of life. The objective of this study is to examine sex differentials in neonatal mortality by detailed ages in a low-income setting.

Design

This is a secondary observational analysis of data.

Setting

Rural Sarlahi district, Nepal.

Participants

Neonates born between 1999 and 2017 in three randomised controlled trials.

Outcome measures

We calculated study-specific and pooled mortality rates for boys and girls by ages (0-1, 1-3, 3-7, 7-14, 14-21 and 21-28 days) and estimated HR using Cox proportional hazards models for male ve
