COVID-19 initially reduced asthma attacks but widened socioeconomic disparities, study finds

A large retrospective study of more than 162,000 asthma patients in the Bronx found that asthma exacerbations dropped sharply after the onset of COVID-19 before rebounding in children but remaining lower in adults. Socioeconomic disparities widened during the pandemic, particularly among Medicaid recipients, certain income groups, and patients with documented unmet social needs, while racial and ethnic gaps persisted without significantly expanding.

Obesity sharply increases hospitalisation risk from infections, global analysis shows

Adult obesity is associated with a substantially higher risk of severe hospital-treated or fatal infections across multiple pathogens, with risk increasing as obesity severity rises. Global modelling suggests roughly one in ten infection-related deaths worldwide may be attributable to adult obesity, although causality cannot be confirmed.

Large Swedish study finds COVID-19 vaccination unrelated to fertility or childbirth rates

A Swedish registry-based cohort study evaluated whether COVID-19 vaccination affected childbirth rates among women aged 18 to 45 years during the pandemic period. No statistically significant association was found between vaccination, childbirth, or recorded miscarriage rates, suggesting demographic and socioeconomic factors likely explain observed fertility trends.

Three daily servings of full-fat dairy do not worsen weight or blood markers

This randomized 12-week trial examined whether adding three daily servings of full-fat dairy to diets aligned with Canada’s Food Guide affects body weight, cardiometabolic markers, and nutrient intake in adults with overweight or obesity. Full-fat dairy intake did not adversely affect weight, body composition, or metabolic health and increased calcium and protein intake, supporting dietary compatibility rather than therapeutic benefit.
