]. The Influence of Age on the Effects of Lifestyle Modification and Metformin in Prevention of Diabetes
Open accessAbstract
BACKGROUND: The incidence of type 2 diabetes increases with age. It is unknown whether interventions to prevent diabetes are as effective in elderly persons as in younger adults. METHODS: The Diabetes Prevention Program (DPP) demonstrated that an intensive lifestyle intervention (ILS) or metformin could prevent or delay diabetes. A predefined secondary outcome of DPP was to determine if treatment effects varied by age. RESULTS: At baseline, participants aged 60-85 years were leaner and had the best insulin sensitivity and lowest insulin secretion compared to younger age groups. Diabetes incidence rates did not differ by age in the placebo group, but ILS was more effective with increasing age (6.3, 4.9, and 3.3 cases per 100 person-years, in the 25-44, 45-59, and 60-85 year age groups, respectively; p(trend) =.007). Participants aged 60-85 years had the most weight loss and metabolic equivalent (MET)-hours of physical activity. The metformin group showed a trend toward higher diabetes incidence among older participants (6.7, 7.7, and 9.3 cases per 100 person-years in the 25-44, 45-59, and 60-85 year age groups, respectively; p(trend) =.07); and diabetes risk increased with age (hazard ratio [age 60-85 vs 25-44] 1.63, p =.02), after adjusting for the greater weight loss in the 60-85 year age group. CONCLUSIONS: Lifestyle modification was exceptionally effective in preventing diabetes in older individuals; this finding was largely explained by greater weight loss and physical activity. The limited effectiveness of metformin in older persons may reflect age-related differences in insulin action and secretion. A lifestyle modification program can be recommended for older individuals at high risk for type 2 diabetes.

TL;DR
In the Diabetes Prevention Program, intensive lifestyle intervention (ILS) prevented diabetes more effectively with increasing age, while metformin showed a borderline trend toward reduced effectiveness in older participants. The age-related ILS advantage was largely explained by greater weight loss and physical activity in the 60–85 year group.
Key findings
- Diabetes incidence in the placebo group did not differ by age (11.0, 10.8, and 10.3 cases per 100 person-years in the 25–44, 45–59, and 60–85 year groups; p = .71).
- ILS became more effective with increasing age: 6.3, 4.9, and 3.3 cases per 100 person-years in the 25–44, 45–59, and 60–85 year groups, respectively (p trend = .007). The 60–85 vs 25–44 hazard ratio was 0.47 (95% CI, 0.28–0.78) in Model 1, but the age difference disappeared after adjusting for time-dependent weight, calorie intake, and activity (HR, 0.83; 95% CI, 0.46–1.50).
- Metformin showed a borderline trend toward higher diabetes incidence with age: 6.7, 7.7, and 9.3 cases per 100 person-years in the 25–44, 45–59, and 60–85 year groups (p trend = .07). In Table 4, the 60–85 vs 25–44 hazard ratio was 1.45 (95% CI, 0.98–2.16) in Model 1 and 1.37 (95% CI, 0.87–2.16) in Model 3.
- Older participants had the most weight loss and physical activity: mean weight change was −6.4 kg in the 60–85 group vs −4.1 kg and −5.0 kg in the younger groups; recreational activity change was 18.7 MET-h/wk vs 4.4 and 5.8 MET-h/wk; 55% vs 33% and 39% reached the 7% weight-loss goal, and 48% vs 34% and 38% reached the 150 min/wk exercise goal.
Methods
- This was a predefined secondary analysis of the Diabetes Prevention Program, a multicenter randomized controlled trial. Participants were aged ≥25 years with impaired glucose tolerance and fasting plasma glucose 95–125 mg/dL; they were randomized to ILS, metformin 850 mg twice daily, or placebo, and followed for an average of 3.2 years.
- For this analysis, participants were divided into three age groups: 25–44, 45–59, and 60–85 years. Diabetes was determined by annual oral glucose tolerance testing and semiannual fasting plasma glucose, with confirmation by a second test.
- Analyses used Kruskal-Wallis tests for baseline characteristics, mixed-effects models for continuous changes, generalized estimating equations for goal attainment, and Cox proportional hazards models for time to diabetes, with linear trend tests and step-down Bonferroni adjustment for pairwise comparisons.
Limitations
- The paper states that ethnic and sex distributions were unequal across age groups, with men and Caucasians over-represented among older participants; the study had limited power to detect age differences in this predefined secondary outcome; and the DPP cohort was relatively healthy and motivated, excluding individuals with significant physical limitations, so results may not apply to frail or disabled elderly persons.
- The paper also states that the numbers precluded meaningful stratified analyses to examine the effect of unequal ethnic and sex distributions in some age groups.
- The text makes evident that age-group comparisons are nonrandomized even though treatment assignment was randomized, so residual confounding by age-related factors cannot be excluded.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
