This study showed that most respondents were within their reproductive age groups and they had the highest proportion of 35.3% while the lowest proportion 6.6% was found among elderly patients (> 60 years). The mean age was 44.87 ± 10.05 years. The preponderance of young adults in this study is consistent with the existing literature which reported that HIV infection is more prevalent among the reproductive age groups, and this was attributed to high risky behaviours within the group.29–31 There were more female respondents 262 (72.2%) than males 101 (27.8%) and this was in tandem with previous studies from Asia and Sub-Sahara Africa (SSA).3,7,32,33This could be because women are more prone to being infected with HIV than their male counterparts.34 Majority of the respondents (67.2%) were married and the most prevalent family type was a monogamous family setting 256 (70.5%).
In this study, the prevalence of depression among respondents was 24.5% using the MINI questionnaire. This is comparable to what was reported by Egbe and colleagues in Abuja, where 28.2% of PLWHA had depression and Ofovwe et al in the University of Benin Teaching Hospital with a 27.3% prevalence.9,35 However, it was lower than the prevalence reported by Adeoti et al (39.6%) in Ado-Ekiti.32 Marwick et al in Tanzania and Balasubramaniam et al in India also reported lower prevalence of 15.5% and 14.0% respectively.36,37 The reasons for the disparity may probably be related to the difference in the sample population and research tools used in their various studies. For instance, the study done in Abuja was a cross-sectional descriptive study involving three HAART clinics across the city with a large sample population of 1,187 and the WHO World Mental Health Composite International Diagnostic Interview questionnaire was used to diagnose depression.35 Likewise Ofovwe et al in Benin City with a sample population of 113, diagnosed depression by using Symptoms Checklist-90 (SCL-90).9 The study by Adeoti et al was conducted among 424 adults PLWHA using Hospital Anxiety and Depression Scales (HADS) to diagnose depression.32 In Tanzania, depression was diagnosed among 220 adults PLWHA using the Clinical Interview Schedule-Revised (CIS-R) questionnaire while in the Indian study, the participants were 208 and the Beck Depression Inventory Ia (BDI-Ia) was used to diagnose depression.36,38 Other reasons for the disparity in prevalence may be due to the effect of high levels of stigmatization, social isolation and rejection towards PLWHA in the various study locations. In addition, the psychological and or emotional disturbance of living with an incurable disease, inadequate family support, unemployment and the incapacitation that could occur in the lives of the respondents may have contributed to the difference in the prevalence of depression in these studies.8,9,39,40 This suggests that depression in adults with HIV/AIDS is a significant comorbidity. The high prevalence of depression among respondents in this study emphasizes the importance of routine screening for CPD and a holistic care approach by the physicians managing PLWHA.
The prevalence of AD in this study was 16.8% using the MINI questionnaire. This is comparable to the finding by Ofovwe et al in Benin City, South-South Nigeria where a prevalence of 15.9% was reported.9 It was lower compared to the findings from the studies conducted by Olagunju et al in Lagos University Teaching Hospital (LUTH) and Adeoti et al in Ado-Ekiti with 21.7% and 32.6% respectively.32,41 In Ethiopia, a higher prevalence of 32.4% was reported by Tesfaw and colleagues while a lower prevalence of 1.4% was reported in India by Balasubramaniam et al among similar respondents.12,37 These variations could be attributed to the differences in the sensitivity of research screening tools used for their studies, the population of respondents, the methodology employed and differences in the geographical locations. Olagunju et al in LUTH assessed AD among 300 respondents in a descriptive cross-sectional study with the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) tool while Adeoti et al used HADS to diagnose AD among 424 respondents.32,41 In Ethiopia, Tesfaw and colleagues also used HADS to diagnose AD among a slightly higher number of respondents (417) than in the index study.12 Balasubramaniam et al in India carried out their study among a larger population of 11,476 over two consecutive years and AD was assessed by the International Classification of Diseases (ICD-10) criteria.37 The finding from this study further revealed the relative presence of AD among PLWHA, therefore, healthcare providers must be aware of this condition and be ready to screen PLWHA to provide holistic care to affected individuals. This will further improve the overall health of the patients and by extension, the nation at large.
AUD prevalence in this study was 0.6% using the MINI screening tool. This lower prevalence could be because the Ilorin metropolis where the study was conducted is predominantly dominated by Muslim faithful whose faith does not permit the consumption of alcohol. Other possibilities include the under-reporting of alcohol use by the participants and the dominance of the female gender among the respondents. This finding is in contrast with the previous research reports from the same geo-political zone (North Central zone, Nigeria) where the higher prevalence of 7.8% and 12% were separately reported by Egbe et al and Farley et al respectively.35,42 Likewise, Gebre and colleagues in West Ethiopia found an 18.4% prevalence of AUD.43 In Southern Brazil, da Silva et al also found a 28.6% prevalence of AUD.44 The disparity may be related to the religious backgrounds of the respondents, economic status, socio-cultural activities, sensitivity of the screening tools, methodology employed and the study population. For instance, the Abuja study by Egbe et al was conducted in a multicentre with 1,187 respondents of different religious backgrounds and socio-cultural beliefs, and the WHO Mental Health Composite International Diagnostic Interview questionnaire was used to diagnose AUD.35 On the other hand, Farley and colleagues conducted their study at the University of Abuja Teaching Hospital and the Alcohol Use Disorder Identification Test (AUDIT) tool was used.42 Other reasons for the differences in prevalence which is in consonance with previously documented wide variations across populations may be due to differences in literacy, unawareness of the effects of alcohol misuse, and occupational status of the population concerned.44
A higher prevalence of depression was found among those with extended family structure (70.4%) than the nuclear family type with a proportion of 55.1%. Generally, there is a dearth of published literature on the association between depression and extended family structure among PLWHA. However, there exist research studies on the relationship between family support and depression among PLWHA. The presence of a higher prevalence of depression among the extended family type in this study was contrary to the existing studies.8,45 The reasons for the higher prevalence of depression among the extended family type in this study could be because too many responsibilities exist within the extended family type, coupled with the absence of a tangible family member who could shoulder such tasks. This might hinder the adequacy of family/social support expected for an HIV-infected family member. In addition, the stigmatization and discrimination associated with HIV disease might prevent infected individuals from disclosing his/her status to family members and this could further worsen the HIV/AIDS disease condition with comorbid psychological stress.
AD was more prevalent (43.3%) among respondents with a nuclear type of family as compared to the extended family structure and the finding was in tandem with the previous study.15,38 The reasons for the similarity could be due to urban settings where the studies were carried out in which the majority of inhabitants were educated and engaged in monogamous types of marriage.
The respondents who had AUD (1.6%) were solely found among the nuclear type of family structure with none among extended family, this is in disparity with the previous studies that reported a higher prevalence of AUD among similar respondents. Egbe et al in Abuja Nigeria reported a 7.8% prevalence of AUD while 14.2% was reported by Bultum et al in the Oromiya region of Ethiopia.35,46 Also da Silva and colleagues in Southern Brazil reported a 28.6% prevalence rate.44 The possible explanation for the low prevalence of AUD in this study could be due to socio-economic, and cultural background and monogamous type of marriage among the respondents. Likewise, the number of respondents recruited for each of the studies, the sensitivity of the screening tools and the methodology employed in the various studies could account for the higher prevalence reported.
