Biochemical Markers

No included intervention showed measurable improvement in biochemical markers. Six interventions assessed biochemical markers including glucose, cholesterol fractions, triglycerides, and HbA1c. Three biochemical marker studies reported no statistically significant changes, and three others did not reach significance likely because of small sample sizes. The review identifies a lack of robust evidence-based interventions that specifically target biochemical outcomes in midlife. The review suggests that midlife metabolic disruptions may require longer or more intensive interventions to change lipid and glucose markers.
