Objective: This study sought to assess the prevalence and correlates of loneliness among in-school adolescents in Ghana using data obtained from the 2012 Global School-based Health Survey conducted in Ghana.

Results: A total of 1 266 in-school adolescents participated in the study. Both descriptive and inferential statistics were used to examine the prevalence and correlates of loneliness. The prevalence of loneliness was 18.4%. Adolescents who felt hungry in-school (AOR = 0.43), those who used tobacco (AOR = 2.31), those who used alcohol (AOR = 1.71), those who felt anxious (AOR = 2.44), those who were bullied (AOR = 1.55), and those who sustained an injury (AOR = 1.33) were more likely to feel lonely than those who did not go hungry in-school, those who did not feel anxious, those who did not use alcohol, and those who did not experience bullying. Adolescents in Senior High School 4, those who were connected (AOR = 0.33), and bonded (AOR = 0.21) to their parents had lower odds of being lonely compared to those in Senior High School 1, those not connected, and those not bonded to their parents.

Conclusion: There is a need for loneliness prevention programs targeting improvement in parental support skills, helping adolescents develop friendship skills, counselling uptake, and prevent bullying victimisation in senior high schools in Ghana.

目标：本研究试图使用从 2012 年在加纳进行的全球学校健康调查中获得的数据，评估加纳在校青少年孤独感的流行程度和相关性。

结果：共有 1 266 名在校青少年参与了这项研究。描述性和推论性统计数据都用于检查孤独感的流行程度和相关性。孤独感的患病率为18.4%。在学校感到饥饿的青少年 (AOR = 0.43)、吸烟者 (AOR = 2.31)、饮酒者 (AOR = 1.71)、焦虑者 (AOR = 2.44)、被欺负者 (AOR = 1.55），受伤的人（AOR = 1.33）比在学校不挨饿的人、不感到焦虑的人、不喝酒的人和不喝酒的人更容易感到孤独经历欺凌。与高中 1 的青少年相比，高中 4 的青少年、那些与父母有联系 (AOR = 0.33) 和有联系 (AOR = 0.21) 的青少年孤独的几率更低，那些没有联系的青少年，

结论：需要针对提高父母支持技能、帮助青少年发展友谊技能、接受咨询和防止加纳高中欺凌受害的孤独预防计划。
