Human Development Index (HDI) vs Higher vs lower HDI categories

Oral health-related quality of life · people aged 60 years and older living in the community

Older adults in higher-HDI countries had better OHRQoL (high 79.9, 95% CI 74.4 to 85.5; very high 78.4, 95% CI 71.1 to 85.8) than those in medium-HDI countries (63.5, 95% CI 54.3 to 72.7); the difference by HDI was statistically significant (ungraded).

Very high Human Development Index (HDI >=0.800) vs High Human Development Index (HDI 0.700-0.799)

Caries experience (mean DMFT) · 12-year-old children across European countries (national/regional epidemiological surveys, 2011-2022)

Mean DMFT was higher in high-HDI (3.41) than very-high-HDI (1.73) countries (ANOVA p<.01); descriptive country-level means only, not meta-analyzed or GRADE-rated.

Odds of higher caries (DMFT) category · 12-year-old children across European countries (national/regional epidemiological surveys, 2011-2022)

HDI was not independently associated with DMFT category in the adjusted model (OR 1.82, 95% CI 0.32 to 10.47); not GRADE-rated.

Populations in countries with a lower Human Development Index (high category, HDI <0.800) vs Populations in countries with a higher Human Development Index (very high, HDI >=0.800)

Caries experience (mean DMFT) · Adults aged 19-60 years

Pooled caries experience (DMFT) was similar in very-high-HDI and high-HDI countries, and meta-regression found no significant association between national HDI and DMFT; ungraded observational evidence with very high heterogeneity.
