Key result
Participants with both hypertension and diabetes (1.3% of the cohort) incurred higher medical costs over 10 years compared to those without either condition or with only one condition.
Why the study?
Does the combination of hypertension and diabetes increase medical costs in community-dwelling individuals?
Cohort (n=4,535)
Does the combination of hypertension and diabetes increase medical costs in community-dwelling individuals?
The combination of hypertension and diabetes significantly increases long-term medical costs compared to having neither condition.
BACKGROUND AND METHODS: A cohort study investigating medical costs associated with the combination of hypertension and diabetes was conducted. The participants included 4535 community-dwelling Japanese individuals, aged 40-69 years, who were classified into the following four categories: 'Neither hypertension nor diabetes', 'Hypertension alone', 'Diabetes alone' or 'Both hypertension and diabetes'. Medical costs per person per month were compared among the four categories. RESULTS AND CONCLUSION: Of the study population, 1.3% had both hypertension and diabetes. During the 10-year follow-up period, participants with both hypertension and diabetes incurred higher medical costs, as compared with those without hypertension, diabetes or their combination, even after adjustment for other confounding factors.

Nakamura et al. (2006) conducted a cohort in Hypertension and/or diabetes (n=4,535). Both hypertension and diabetes vs. Neither hypertension nor diabetes, hypertension alone, or diabetes alone was evaluated on Medical costs per person per month. Participants with both hypertension and diabetes (1.3% of the cohort) incurred higher medical costs over 10 years compared to those without either condition or with only one condition.
