Genetic and Environmental Contributions of Primary Angle-Closure Glaucoma and Primary Open-Angle Glaucoma: A Nationwide Study in Taiwan

PURPOSE

To estimate the familial risks of primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) and assess the relative contributions of environmental and genetic factors to these risks.

DESIGN

Retrospective, population-based cohort study.

METHODS

We used the 2000-2017 Taiwan National Health Insurance Program database to construct 4,144,508 families for the 2017 population (N = 23,373,209). We used the polygenic liability model to estimate glaucoma's heritability and familial transmission. The degree of familial aggregation of glaucoma was obtained from the adjusted relative risk for individuals whose first-degree relatives had glaucoma using Cox's model.

RESULTS

PACG and POAG prevalence rates for individuals whose first-degree relatives had PACG or POAG were 0.95% and 2.40%, higher than those of the general population (0.61% and 0.40%, respectively). The relative risk of PACG in individuals whose first-degree relatives had PACG was 2.44 (95% CI = 2.31-2.58). The relative risk of POAG in individuals whose first-degree relatives had POAG was 6.66 (95% CI = 6.38-6.94). The estimated contributions to PACG and POAG phenotypic variances were 19.4% and 59.6% for additive genetic variance, 19.1% and 23.2% for common environmental factors shared by family members, and 61.5% and 17.2% for nonshared environmental factors, respectively.

CONCLUSIONS

These data highlight the relative importance of genetic contribution to POAG and environmental contribution to PACG. Therefore, future work may need to focus on finding more novel environmental determinants of PACG.

Marital satisfaction and emotional divorce among Iranian married individuals: A survey of hospital visitors of nine provinces

BACKGROUND

Evidence is accumulating that the pattern and nature of marital relationships are very different in different cultures. This nationwide study aimed to determine marital satisfaction and the prevalence of emotional divorce as well as to identify the sociodemographic correlates in a Muslim population.

MATERIALS AND METHODS

In this cross-sectional study, one-third of Iran's provinces were selected randomly and a representative sample of inhabitants of their central city was included in the study. The ENRICH marital satisfaction scale was used to determine marital satisfaction levels. A single-item measure with confirmed validity and reliability was used to find out about emotional divorce. The demographic variables included respondent's age, spouse's age, gender, educational level, residency, childbearing, and premarriage familiarity.

RESULTS

Of the 2033 participants, 1034 were women (50.9%). Nearly one-third of both men and women had academic degrees. Almost 53% of them were satisfied with their marital life and 9.7% had emotional divorce. Men with academic degrees had a higher probability of marital satisfaction (odds ratio [OR] =1.26, 95% confidence interval [CI]: 1.04-1.53) and a lower prevalence of emotional divorce (OR = 0.37, 95% CI: 0.24-0.58).

CONCLUSION

This study showed a relatively high percentage of marital dissatisfaction as well as emotional divorce. Policymakers should strengthen premarriage education programs and postmarriage counseling centers.
