What the research found
The Journal of Exercise Science & Fitness, October 2026, article 200516, reports National Health Interview Survey data from 1997 through 2018 linked to mortality records through 31 December 2019. Cardiometabolic multimorbidity meant at least two of heart disease, diabetes, and stroke. The sample was 15,079 adults, including 8,299 women (55 percent). Mean follow-up was 10.1 years, with 6,932 deaths. Versus inactive adults, the hazard ratio was 0.81 (0.75 to 0.89) for people who were insufficiently active, 0.64 (0.49 to 0.83) for a weekend pattern of at least 150 minutes a week in one or two sessions, and 0.60 (0.55 to 0.65) for people who were regularly active at least 150 minutes a week across three or more sessions. The estimated life expectancy gaps at age 45 were 2.24, 4.60, and 4.94 years. At age 65 they were 1.46, 3.04, and 3.27 years. The same weekly physical activity is what the categories describe. The study is observational and does not show that bunching that activity into fewer sessions causes a longer life. Not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
