TL;DR

Greater weight at birth, in childhood, and in late adolescence were all associated with greater risk of NHL, and overall associations did not substantively vary by major NHL subtype.

Abstract

Simple Summary Perinatal and early-life factors have been hypothesized to influence non-Hodgkin lymphoma (NHL) risk, but study results have been mixed and exposure data for childhood ages are limited. In this case–control study of 2280 NHL cases and 2253 controls, we assessed perinatal and early-life factors in association with risk of developing NHL later in life. Greater weight at birth, in childhood, and in late adolescence were all associated with greater risk of NHL. Breastfeeding duration of >6 months compared to never being breastfed was inversely associated with NHL risk. We did not observe any statistically significant associations for other perinatal and early life factors evaluated, and overall associations did not substantively vary by major NHL subtype. Excess body weight across the life course, including in early life, may influence risk of developing NHL later in life.

Life-Course Timing of Family Bereavement and Cognitive Impairment in Midlife to Later Life.

Among individuals who experienced family member deaths, losses occurring at younger ages were associated with higher risks of cognitive impairment than losses occurring at older ages, and there was no evidence of racial/ethnic or gender differences in these patterns.

Pregnancy loss, healthy lifestyle behaviours, and long-term risk of hospital-treated infections: a prospective cohort study

PL was associated with a higher long-term risk of hospital-treated infections, while adherence to a healthy lifestyle was associated with a substantially lower risk and partially attenuated the excess infection risk associated with PL, highlighting the potential importance of lifestyle modification for long-term infect...

Parental son preference in childhood and sex differences in the risk of cardiovascular disease in middle-aged and older adults.

INTRODUCTION Sex differences in cardiovascular disease (CVD) risk are examined through biological and clinical factors, with less attention to early-life social exposures. This study examined associations of childhood parental son preference with CVD risk, sex differences, and mediation by modifiable risk factors. ME...

A History of Pregnancy Loss is a Risk Factor for Severe Maternal Morbidity in a First Live Birth: A Retrospective Cohort Study

Prior pregnancy loss is associated with modest but consistent elevation in severe maternal morbidity during a subsequent delivery, which may reflect shared underlying maternal risk, effects related to prior loss, or both.
