Dietary B Vitamins and Depression in Persons with Human Immunodeficiency Virus Infection: The Positive Living with HIV (POLH) Study

B vitamins have beneficial roles in mental health functional impairments; however, research on the role of B vitamins in depression among HIV-infected persons is limited. This study assessed the association between dietary B vitamin intake and depressive symptoms in a cohort of HIV-infected persons. A cross-sectional survey was conducted among 314 HIV-infected persons (180 men and 134 women) aged 18 to 60 y residing in the Kathmandu, Nepal. The Beck Depression Inventory-I was used to measure depression, with a cutoff score of 20 or higher. Dietary intake was assessed using two nonconsecutive 24-h dietary recalls. The relationships between B vitamins and depressive symptoms were assessed using multiple logistic regression analysis. Twenty-six percent participants (men: 23%; women: 29%) were depressed. More than two thirds of participants’ B vitamins intake were below the estimated average requirements (EAR) level. Low intake of riboflavin was associated with an increased risk of depression in women but not in men. Multivariate OR (95% CI) for depression in the first, second, and third tertiles of riboflavin in total participants were 1 (reference), 0.87 (0.46–1.64), and 0.49 (0.24–0.98), respectively (p for trend = 0.048) and in women were 1 (reference), 0.94 (0.36–2.40), and 0.23 (0.07–0.77), respectively (p for trend = 0.020). No clear associations were seen between other B vitamins and depressive symptoms in either sex. Low intake of riboflavin was independently associated with an increased risk of depressive symptoms in all participants and in HIV-infected women. Further prospective studies are warranted to confirm the role of vitamin B vitamins in depressive symptoms among HIV-infected persons

Delays in Antiretroviral Therapy Initiation Among HIV-Positive Individuals: Results of the Positive Living with HIV Study

Background: Lack of early initiation of antiretroviral therapy (ART) remains a major health concern due to increased risk of premature mortality and further HIV transmission. This study explored CD4+ cell count monitoring in relation to delays in ART initiation among HIV-positive individuals in the Kathmandu Valley, Nepal, where ART coverage was only 23.7% in 2011. Design: We recruited a total of 87 ART-naïve, HIV-positive individuals aged 18 to 60 years through the networks of five non-government organizations working with HIV-positive individuals. We collected data on the history of ART initiation, CD4+ cell count monitoring, socio-demographic variables, perceived family support (measured with 10-item Nepali Family Support and Difficulty Scale), depression, and HIV symptom burden. Correlates of ART eligibility were examined using multivariable logistic regression analysis. Results: A total of 72 of the 87 ART-naïve participants (82.8%) had monitored their CD4+ cell count in the past 6 months. Of these, 36 (50%) participants were eligible for ART initiation with CD4+ cell count /mm3. A total of 12 participants had CD4+ cell count /mm3. Lower level of perceived family support was associated with 6.05-fold higher odds (95% confidence interval =1.95 to 18.73) of being ART eligible with a CD4+ cell count /mm3. Conclusions: High rate of delays in ART initiation and the strong association of low perceived family support with ART eligibility in our study participants suggest that HIV service providers should consider the role and impact of family support in influencing individual decisions to initiate ART among eligible HIV-positive individuals

Perceived Family Support and Antiretroviral Adherence in HIV-Positive Individuals: Results from a Community-Based Positive Living With HIV Study

The purpose of this study was to examine the association between perceived family support, either positive or negative, and adherence to antiretroviral medication regimens among HIV-positive individuals in the Kathmandu Valley, Nepal. We measured past 3-month antiretroviral adherence among 233 HIV-positive individuals, in relation to perceived family support, both positive (in terms of emotional and instrumental support) and negative (in the form of negative interactions), using the 10-item Nepali Family Support and Difficulty Scale. Medium and high levels of perceived emotional support from family were associated with reduced risk of antiretroviral nonadherence, compared with low levels of perceived emotional support (adjusted odds ratio [AOR] ¼ 0.37, 95% confidence interval [CI] [0.16, 0.88], and AOR ¼ 0.23, 95% CI [0.08, 0.64], respectively). Conversely, higher levels of felt emotional distance (AOR ¼ 1.46, 95% CI [1.00, 2.14]) and experienced physical harm (AOR ¼ 2.04, 95% CI [1.07, 3.91]) were associated with increased risk of nonadherence. The results support the recommendation that service providers need to be aware of the significant role of family support in shaping antiretroviral adherence and to consider ways to strengthen positive family support while minimizing negative family interactions to increase adherence rates

Reaching hard-to-reach migrants by letters: An HIV/AIDS awareness programme in Nepal

We assessed the impact of an HIV/AIDS programme for Nepalese migrants to India that involved writing letters. The programme created opportunities for sending HIV/AIDS-related messages to the migrants in India, and encouraging them practicing safer sex. Initially, they received the messages only from the programme, but later from their colleagues, spouses or other family members. They discussed the messages in groups, disseminated them, and sought more knowledge in their destinations. These findings indicated that using letters could be an effective way to reach inaccessible migrants at their destinations, and help them to improve their HIV/AIDS-related knowledge, and safer sex practices

Knowing the Consequences of Unprotected Sex with Seroconcordant Partner Is Associated with Increased Safer Sex Intentions among HIV-positive Men in Kathmandu, Nepal

Unprotected sexual intercourse among HIV-positive people can adversely affect their own health by increasing their exposure to multiple strains of HIV-1 or other sexually transmitted infections (STIs). The study explored the relationship between knowledge of Nepalese HIV-positive men about the consequences of having unprotected sex with seroconcordant partners and their intention to practise safer sex with such partners. In total, 166 participants recruited conveniently in the Kathmandu Valley, Nepal, were interviewed. Each participant reported intention to practise safer sex with seroconcordant partners, know-ledge about the consequences of having unprotected sex with seroconcordant partners, perceived partner-related barriers to condom-use, belief that condoms interfere with sex, and condom-use self-efficacy. Of the 166 participants, 50.6% intended to practise safer sex every time they have sex with seroconcordant partners. Results of multiple logistic regression analysis showed that the participants who were aware of the possibility of HIV superinfection [adjusted odds ratio (AOR)=2.93, 95% confidence interval (CI) 1.16-7.34, p=0.022)] or that the presence of STIs in HIV-positive persons increases progression of HIV disease (AOR=2.80, 95% CI 1.08-7.26, p=0.033) were more likely to intend to practise safer sex with seroconcordant partners. Similarly, the participants who were employed or who had lower levels of belief that condoms interfere with sex were more likely to intend to practise safer sex. The findings suggest that improving the knowledge of HIV-positive persons about the consequences of having unprotected sex with seroconcordant partners might improve their intention to practise safer sex with such partners

Coinfection with Hepatitis C Virus among HIV-Positive People in the Kathmandu Valley, Nepal

Background: Previous research has studied the rate of hepatitis C virus (HCV) coinfection among HIV-positive people regardless of their antiretroviral therapy (ART) status. Our objectives were to measure the seroprevalence of HCV both in HIV-positive people receiving ART and in those not receiving ART and to describe the characteristics of coinfected people in the Kathmandu Valley, Nepal. Methods: We conducted a cross-sectional survey of 319 HIV-positive people residing in the Kathmandu Valley, Nepal. We screened the participants’ serum samples for HCV antibodies using the Latex Photometric Immunoassay based on third-generation assay. Results: A total of 138 (43.3%) participants were HCV positive. The prevalence of HCV coinfection was 96.2% (125 of 130) among participants with lifetime injection drug use (IDU). Among participants not receiving ART, the coinfection rate was 58.1% (50 of 86) compared with 37.8% (88 of 233) among those receiving ART. In multivariable analysis, participants who reported lifetime IDU and were current smokers were more likely to have HCV coinfection. The adjusted odds ratio (AOR) of HCV coinfection for ART was decreased, although it was not statistically significant (AOR ¼ 0.45; 95% confidence interval ¼ 0.13-1.48). Conclusion: The high prevalence of HCV coinfection among both individuals receiving ART and those not receiving ART suggests that screening for HCV among HIV-positive people would be useful, in particular, for those with lifetime IDU and soon after their HIV diagnosis

Serum 25-Hydroxyvitamin D Levels and C-Reactive Protein in Persons with Human Immunodeficiency Virus Infection

Human immunodeficiency virus (HIV) infection has frequently been associated with vitamin D deficiency as well as chronic inflammatory response. We tested the hypothesis of an independent relationship between serum concentrations of 25-hydroxyvitamin D [25(OH)D] and high-sensitivity C-reactive protein (CRP) in a cohort of HIV-positive people. A cross-sectional survey was conducted among 316 HIV-positive people (181 men and 135 women) aged 16 to 60 years residing in the Kathmandu Valley, Nepal. Serum high-sensitivity CRP concentrations and serum 25(OH)D levels were measured by the latex agglutination nephelometry method and the competitive protein-binding assay, respectively. The relationship between serum CRP concentrations and 25(OH)D serum level was assessed using multiple logistic regression analysis with adjustment of potential cardiovascular and HIV-related factors. The proportions of participants with 25(OH)D serum levels \u3c 20 ng/ml, 20–30 ng/ml, and ‡ 30 ng/ml were 83.2%, 15.5%, and 1.3%, respectively. The mean 25(OH)D serum levels in men and women were 15.3 ng/ml and 14.4 ng/ml, respectively. Participants with a 25(OH)D serum level of \u3c 20 ng/ml had a 3.2-fold higher odds of high CRP ( \u3e 3mg/liter) compared to those with a 25(OH)D serum level of ‡ 20 ng/ml ( p = 0.005). Men and women with a 25(OH)D serum level of \u3c 20 ng/ml had 3.2- and 2.7-fold higher odds of high CRP ( \u3e 3mg/liter), respectively, compared to those with a 25(OH)D serum level of ‡ 20 ng/ml. The relationships remained significant only in men ( p = 0.02) but not in women ( p = 0.28). The risk of having a high level of inflammation (CRP \u3e 3mg/liter) may be high among HIV-positive men and women with a 25(OH)D serum level of \u3c 20 ng/ml

Assessing the quality of service of village malaria workers to strengthen community-based malaria control in Cambodia

BackgroundMalaria continues to be a major public health problem in remote forested areas in Cambodia. As a national strategy to strengthen community-based malaria control, the Cambodian government has been running the Village Malaria Worker (VMW) project since 2001. This study sought to examine the nature and quality of the VMWs\u27 services.MethodsData collection was carried out in February and March 2008 through interviews with one of the two VMWs who takes the lead in malaria control activities in each of the 315 VMW villages (n = 251). The questionnaire addressed 1) the sociodemographic characteristics of VMWs, 2) service quality, 3) actions for malaria prevention and vector control, and 4) knowledge of malaria epidemiology and vector ecology.ResultsVMWs were effective in conducting diagnosis with Rapid Diagnostic Tests (RDTs) and prescribing anti-malarials to those who had positive RDT results, skills that they had acquired through their training programmes. However, most other services, such as active detection, explanations about compliance, and follow-up of patients, were carried out by only a small proportion of VMWs. The variety of actions that VMWs took for malaria prevention and vector control was small (average action index score 12.8/23), and their knowledge was very limited with less than 20% of the VMWs giving correct answers to six out of seven questions on malaria epidemiology and vector ecology. Knowledge of vector breeding places and malaria transmission were significant determinants of both the quality of VMWs\u27 services and the variety of their actions for malaria prevention and vector control.ConclusionsVMWs\u27 services focused primarily on diagnosis and treatment. Their focus needs to be broadened to cover other aspects of malaria control in order to further strengthen community-based malaria control. VMWs\u27 actions and knowledge also need substantial improvement. Strengthening training programmes can help achieve better performance by VMWs

Perceived Family Support and Depression among People Living with HIV/AIDS in the Kathmandu Valley, Nepal

Background: Depression is emerging as a highly prevalent psychiatric condition among people living with HIV/AIDS (PLWHA). Perceived family support (PFS) buffers depression among chronic disease patients. However, a similar relationship among PLWHA is unexplored. Objective: To examine the relationship between PFS and depression among PLWHA in the Kathmandu Valley, Nepal. Methods: In this cross-sectional study, depression was measured by Beck Depression Inventory Ia. Perceived family support was measured by Nepali Family Support and Difficulties Scale. The status of depression was compared between 208 PLWHA and 208 HIV-negative participants. The relationship between PFS and depression was examined only among PLWHA. Results: Among each of the 208 participants, the number of depressed PLWHA (n ¼ 61,29.3%) was higher than that of HIV-negative participants (n ¼ 13,6.2%; P \u3c .001). Perceived family support had a negative association with depression in PLWHA (adjusted odds ratio [AOR] ¼ 0.20, 95% confidence interval [CI] ¼ 0.08-0.53). Conclusion: In Nepal, PLWHA display a higher level of depression than HIV-negative people, and a lower level of PFS is associated with depression among PLWHA. Improved family support might be helpful in reducing depression among Nepalese PLWHA
