Mental illness and obesity (MH-OB) may co-occur in adolescence and have a strong risk to track into adulthood. Using an intersectional framework, we explored associations between ethnic-sexual identities and MH-OB comorbidity in adolescents. We examined the risk of self-harm (SH) and attempted suicide (AS) by comorbidity status and ethnic-sexual identities.
Participants included 9,789 adolescents (aged 17 years) from the UK-wide Millennium Cohort Study with data on self-identified ethnicity and sexuality. Participants were categorised as White-heterosexual, White-sexual minority (SM), Ethnic Minority (EM) heterosexual or EM-SM adolescents. We used multivariable logistic regression to examine associations between 1.dual ethnic-sexual identities and MH-OB comorbidity, 2.risk for self-harm (or attempted suicide) in relation to comorbidity and ethnic-sexual identities (including interactions between the comorbidity and ethnic-sexual identities variables to assess whether risk for self-harm differed by ethnic-sexual identities and comorbidity status).
Comorbidity was higher among White-SM (OR = 3.73, 95%CI 2.42-5.75) and EM-SM (OR = 1.96, 1.03-3.73) adolescents. SM identities (OR = 3.02, 2.41-3.78 for White-SM) and having comorbidity (OR = 2.83, 2.03-3.95) were independently associated with SH or AS. Risk of SH among White-heterosexual individuals was greater among comorbid individuals (40%) relative to non-comorbid individuals (19%). Risk of SH was higher in SM individuals (58% vs. 41% in White-SM and 50% vs. 29% in EM-SM individuals with and without comorbidity, respectively). Risk of AS was 5% and 19% in comorbid and non-comorbid White-heterosexual individuals, respectively; the corresponding figures for White-SM individuals were 14% and 17%.
Irrespective of ethnicity, SM adolescents have a significantly greater risk of SH and AS. Comorbidity further amplifies this risk.
精神疾病和肥胖症(MH-OB)可能在青少年时期同时发生,并具有很强的风险追踪到成年期。使用交叉框架,我们探讨了青少年时期种族性别认同与 MH-OB 共病之间的关联。我们检查了共病状态和种族性别认同与自伤(SH)和自杀未遂(AS)风险之间的关系。
参与者包括来自英国全国千年队列研究的 9789 名青少年(年龄为 17 岁),他们的数据包括自我认同的种族和性别。参与者被归类为白人异性恋者、白人少数性取向者(SM)、少数族裔(EM)异性恋者或 EM-SM 青少年。我们使用多变量逻辑回归来检验 1.双重种族性别认同与 MH-OB 共病之间的关联,2.与共病和种族性别认同相关的自伤(或自杀未遂)风险(包括共病和种族性别认同变量之间的相互作用,以评估自伤风险是否因种族性别认同和共病状态而异)。
白人 SM(OR=3.73,95%CI 2.42-5.75)和 EM-SM(OR=1.96,1.03-3.73)青少年的共病率较高。SM 身份(OR=3.02,2.41-3.78 对于白人 SM)和共病(OR=2.83,2.03-3.95)与 SH 或 AS 独立相关。白人异性恋个体中,共病个体(40%)相对于非共病个体(19%)SH 风险更高。SM 个体的 SH 风险更高(在白人 SM 个体中,共病个体为 58%,非共病个体为 41%,在 EM-SM 个体中,共病个体为 50%,非共病个体为 29%)。共病和非共病白人异性恋个体中 AS 的风险分别为 5%和 19%;对于白人 SM 个体,相应的数字分别为 14%和 17%。
无论种族如何,SM 青少年的 SH 和 AS 风险显著增加。共病进一步放大了这种风险。
