Background The plight of orphans, exacerbated by conflict, disease, and socioeconomic factors, remains a pressing global issue, particularly in sub-Saharan Africa. Nigeria, notably impacted by the HIV/AIDS epidemic, terrorism, and natural disasters, has witnessed a substantial increase in orphan populations. These children face severe challenges, including child abuse, malnutrition, limited access to education, stigmatization, and a range of psychological and behavioural disorders. Despite some interventions, orphanages primarily address material needs, often neglecting comprehensive medical, social, and psychosocial support. This study explores the behavioural patterns of orphans in Kaduna, Nigeria, and examines how their medical and social challenges compare across various orphanages. Methodology A cross-sectional, comparative analysis was conducted among 100 orphans from selected orphanages in Kaduna. Data were collected through interviewer-administered questionnaires assessing socio-demographics, medical conditions, behavioural patterns, stigma, psychosocial status, and coping strategies. Results The mean age of respondents was 10 years, with 68% being male. Nutritional issues were prevalent, with 53.7% classified as underweight despite 54.9% reportedly consuming balanced diets. Medical concerns were significant, with 33.7% showing clinical signs of illness and 46.7% not fully immunized. Behavioural issues were prominent, including hyperactivity symptoms (27.0%), enuresis (22.3%), and depressive symptoms (1.8%). Socially, most respondents (83.3%) reported positive peer relationships, though bullying (11.4%) and stigmatization (9%) were also observed. Educational access was generally high, with only 2.2% not attending school. However, social support systems varied, with 35.2% reporting strong support and 46.8% adapting their goals as a coping mechanism. Conclusion The findings highlight the complex medical and behavioural challenges faced by orphans in Kaduna's orphanages, underscoring the need for integrated interventions that provide medical, psychosocial, and educational support. A holistic approach is crucial to improving their overall well-being and future prospects.
