Multinomial logistic regression, single and combined models, examining the relationship between sleep (duration, insomnia, and sleepiness) and neighbor helping behavior (often/always, sometimes, and rarely/never), adjusting for age, sex, race/ethnicity, income, and education (N =1,007).

^†Insomnia was scored as “none” for participants who scored 0 to 7 on the ISI, as “mild” for participants who scored 8 to 14 on the ISI, and “moderate-severe” for participants who scored 15 to 28.

^‡Sleepiness was scored as “high” for participants who scored 10 or higher on the ESS.
