The associations among orphans' subjective happiness, sociodemographic characteristics, and satisfaction with daily life were assessed to identify their essential needs. A structured questionnaire survey was performed among orphans aged 10-19 years old in Nigeria. Logistic regression analysis was performed to determine the associations among subjective happiness with actual living conditions, orphanhood status, daily life activities, relationships with current caregivers, and sociodemographic information. A total of 658 respondents aged 14.7±2.3 years (mean±SD) participated in the present study. The study participants who showed positive feelings of happiness were those who had 3 meals per day (P<0.001), the same/greater number of meals per day than other family members (P<0.001), were not committed to working activities (P<0.01), who lived together with larger numbers of children (P<0.01), who had good relationships with their current caregivers (P<0.001), and who felt they were treated without discrimination in the community (P<0.001). To increase orphans' satisfaction with their actual living conditions, the quality of basic needs in daily life must be improved. Programs regarding care and support of orphans should focus on community partners in supporting such underserved children and their caregivers.
