Table 4.

Participation in social activities (%) by self-rated vision and hearing, and unmet needs.

Participation (%) of social activity	All restricted sample	By vision capacity		By hearing capacity		By DSL		By needs for glasses		By needs for hearing aids
By social activity type	Average	Good vision	Poor/fair vision	Good hearing	Poor/fair hearing	Without DSL	DSL	Good vision or with glasses	Unmet needs for glasses	Good hearing or with health aids	Unmet needs for hearing aid
Social activity: any (yes)	54.9	58.5	54.1*	58.9	52.8*	58.1	52.5*	60.3	50.5*	58.7	52.8*

The numbers reported here are the weighted proportions (%) of respondents who have reported participation in any social activities. These numbers are calculated based on the restricted sample (7,212 respondents) used in the final regression models. The differences in this table are all statistically significant at a significant level 5% (as indicated by *), except for the insignificant correlation between poor/fair vision and social activity of helping others. The reference groups for the comparisons of differences in proportions are: good vision, good hearing, without DSL, good vision or with glasses, good hearing or with health aids.
