Prevalence and Correlates of Vitamin D Deficiency Among Children and Adolescents From a Nationally Representative Survey in India.

OBJECTIVE: To evaluate the prevalence of vitamin D deficiency (VDD) and its correlates among apparently healthy children and adolescents. METHODS: We carried out a secondary analysis of data of Comprehensive National Nutrition Survey 2016-18 to analyze the pre-valence and predictors of VDD among Indian children and adolescents. RESULTS: The over-all prevalence of VDD in preschool children (1-4 years), school age (5-9 years) children, and adolescents (10-19 years) was 13.7%, 18.2%, and 23.9%, respectively. Age, living in urban area, and winter season were significantly associated with VDD. Vegetarian diet and high-income households were the main risk factors observed in 5-19 years age category. Female sex and less than three hour of physical activity/week were independent risk factors among adolescents. CONCLUSION: The prevalence and determinants of VDD across different age-groups are reported, and these should be interpreted and addressed to decrease the burden of VDD in India.

Prevalence of metabolic syndrome among adolescents in India: a population-based study.

BACKGROUND: In India, the prevalence of overweight among adolescents is on the rise, setting the stage for an increase in metabolic syndrome (MS). This paper presents the national prevalence of MS in adolescents in India. METHODS: A nationally representative data of adolescents (10-19 years) from the Comprehensive National Nutrition Survey was used. MS was defined based on the NCEP-ATP III criteria for adolescents. Bivariate analysis was used to report socio-demographic differentials in prevalence and to assess interstate variability. Multivariate logistic regression model was constructed to measure the association between socio-demographic characteristics and prevalence of MS. Census data from 2011 was projected to 2017 to calculate burden. RESULTS: The prevalence of MS was 5.2% among adolescents. 11.9%, 15.4%, 26.0%, 31.9% and 3.7% had central obesity, high blood pressure, hypertriglyceridemia, low HDL-cholesterol and high fasting glucose, respectively. The prevalence was higher among males (5.7% vs. 4.7%, adjusted odds ratio (AOR): 1.3, 95% confidence interval [CI]: 1.0, 1.6), those residing in urban areas (7.9% vs 4.2%, AOR: 1.4, 95% CI: 1.1, 1.8), and from wealthier households as compared to their counterparts (8.3% vs. 2.4%, AOR: 3.4, 95% CI: 2.1, 5.5). There was wide interstate variability in the prevalence of MS (0.5% - 16.5%). In 2017, 14.2 million adolescents had MS in India. CONCLUSIONS: The prevalence of MS among adolescents in India is low and clustered in urban areas and richer households. Early prevention interventions promoting a healthy lifestyle, especially in high prevalence areas, are needed to keep MS from becoming a public health issue.

Client Experiences in a Mobile-Phone Counseling Intervention for Enhancing Access to Prevention of Mother To-Child Transmission (PMTCT) Services in Kenya.

Background: The prevention of mother-to-child transmission (PMTCT) is considered one of the most successful HIV prevention strategies in detecting and reducing HIV acquisition in utero or at birth. It is anticipated that with the increasing growth of digital technologies mobile phones can be utilized to enhance PMTCT services by improving provider-client interactions, expanding access to counseling services, and assisting in counteracting social and structural barriers to uptake of PMTCT services. Understanding the subjective experiences of women accessing PMTCT services in different settings has the potential to inform the development and promotion of such methods. This paper explores the perspectives of HIV-positive pregnant women attending maternal and neonatal clinic services in Kisumu, Kenya. Methods: Data are reported from in-depth interviews with women, following a longitudinal study investigating the impact of a structured, counselor-delivered, mobile phone counseling intervention to promote retention in care and adherence to ARV prophylaxis/treatment, for HIV-positive pregnant women. Thematic content analysis was conducted. Results: Discussions indicated that mobile-phone counseling provided useful health-related information, enhanced agency, and assisted mothers access critical PMTCT services across the cascade of care. Similarly, mobile-phone counseling offered personalized one-to-one contact with trained health providers including facilitating discussion of personal issues that likely affect access to services. Findings also identified barriers to the uptake of services, including a lack of partner support, poor health, poverty, facility-related factors, and provider attitudes. Discussion: Overall, findings show that mobile-phone counseling is feasible, acceptable, and can enhance access to PMTCT services by overcoming some of the individual and facility-level barriers. Although mobile-phone counseling has not been routinized in most health facilities, future work is needed to assess whether mobile-phone counseling can be scaled-up to aid in the effective use of HIV and PMTCT services, as well as improving other related outcomes for mother and child dyad.

Association of maternal height and body mass index with nutrition of children under 5 years of age in India: Evidence from Comprehensive National Nutrition Survey 2016-18.

BACKGROUND AND OBJECTIVES: Child undernutrition remains an area of public health concern across the globe, particularly in developing countries like India. Previous studies have focused on the association of maternal nutrition with premature pregnancy and birthweight of child, with few establishing the intergenerational effect but limited to select populations and geography. METHODS AND STUDY DESIGN: This study used data from 35,452 children aged under 5 years and their biological mother from nationally representative Comprehensive National Nutrition Survey (CNNS) in India. The outcome variables were anthropometric indices: height-for-age, weightfor- height, and weight-for-age. The exposure variables were maternal height and body mass index (BMI). Multivariate regression analysis was used to examine the association between maternal height and BMI with child undernutrition. RESULTS: Out of total number of mothers, 11.1% were short in stature and 28% were underweight. Of total number of children, 33.9%, 17.3% and 32.7% were stunted, wasted, and underweight respectively. Children born to mother with short stature were more likely to be stunted (OR=1.73, 95% CI 1.59-1.89), wasted (OR=1.26, 95% CI 1.12-1.41) and underweight (OR=1.64, 95% CI 1.50-1.79). Similarly, children with underweight mother were more likely to be stunted (OR=1.63, 95% CI 1.53-1.73), wasted (OR=1.64, 95% CI 1.52-1.77) and underweight (OR=2.14, 95% CI 2.01-2.27). CONCLUSIONS: The study shows a strong association between maternal and child undernutrition demonstrating intergenerational linkage between the two. The national programme needs to focus on holistic and comprehensive nutrition strategy with targeted interventions to improve both maternal and child health.

Waist circumference, waist-to-height ratio and BMI percentiles in children aged 5 to 19 years in India: A population-based study.

OBJECTIVE: Nationally representative percentiles for waist circumference (WC), waist-to-height-ratio (WHtR), and body mass index (BMI) are not available for children and adolescents in India. METHODS: Using LMS method, age- and gender-specific reference growth charts were constructed for WC (n = 68,261), WHtR (n = 68,261), and BMI (n = 67,741) from children/adolescents aged 5-19 years who participated in a nationally representative survey. General obesity, indicating overall obesity, was defined as age-sex-specific BMI z-scores ≥ 95th percentile. Central obesity was defined in three ways: WC ≥ 90th percentile, WHtR ≥ 0.5, and both WC ≥ 90th percentile and WHtR ≥ 0.5. FINDINGS: WC and BMI percentiles for boys and girls are lower than those previously reported from India and several other countries. The BMI percentiles are lower than the WHO 2007 reference population. The prevalence of general obesity using India specific BMI centiles was 2.9% (95% CI: 2.6-3.2). The prevalence of central obesity was 6.1% (95% CI: 5.7-6.6) using WC ≥ 90th percentile, 5.3% (95% CI: 5.0-5.7) using WHtR ≥ 0.5, and 3.6% using both criteria. Three-fourth of children with general obesity also had central obesity based on WC ≥ 90th. CONCLUSIONS: Indian children are thinner than Caucasian and other Asian children, and the global WHO reference population. Using India specific reference, the prevalence of central obesity is higher than general obesity with a significant overlap between the two.

Socio-economic inequality in anthropometric failure among children aged under 5 years in India: evidence from the Comprehensive National Nutrition Survey 2016-18.

BACKGROUND: Conventional indicators used to access the nutritional status of children tend to underestimate the overall undernutrition in the presence of multiple anthropometric failures. Further, factors contributing to the rich-poor gap in the composite index of anthropometric failure (CIAF) have not been explored. This study aims to estimate the prevalence of CIAF and quantify the contribution of factors that explain the rich-poor gap in CIAF. METHODS: The present study used data of 38,060 children under the age of five years and their biological mothers, drawn from the nationally representative Comprehensive National Nutrition Survey of children and adolescents aged 0-19 years in India. The CIAF outcome variable in this study provide an overall prevalence of undernutrition, with six mutually exclusive anthropometric measurements of height-for-age, height-for-weight, and weight-for-age, calculated using the World Health Organization (WHO) Multicenter Growth Reference Study. Multivariate regression and decomposition analysis were used to examine the association between covariates with CIAF and to estimate the contribution of different covariates in the existing rich-poor gap. RESULTS: An overall CIAF prevalence of 48.2% among children aged aged under 5 years of age was found in this study. 6.0% children had all three forms of anthropometric failures. The odds of CIAF were more likely among children belonging to poorest households (AOR: 2.41, 95% CI: 2.12-2.75) and those residing in urban area (AOR: 1.06, 95% CI 1.00-1.11). Children of underweight mothers and those with high parity were at higher risk of CIAF (AOR: 1.51, 95% CI: 1.42-1.61) and (AOR: 1.15, 95% CI: 1.08-1.22), respectively. Children of mother exposed to mass media were at lower risk of CIAF (AOR: 0.87, 95% CI: 0.81-0.93). CONCLUSION: This study estimated a composite index to assess the overall anthropometric failure, which also provides a broader understanding of the extent and pattern of undernutrition among children. Findings show that maternal covariates contribute the most to the rich-poor gap. As well, the findings suggest that intervention programs with a targeted approach are crucial to reach the most vulnerable groups and to reduce the overall burden of undernutrition.

The Effects of a Single Freeze-Thaw Cycle on Concentrations of Nutritional, Noncommunicable Disease, and Inflammatory Biomarkers in Serum Samples.

Background The stability of biological samples is vital for reliable measurements of biomarkers in large-scale survey settings, which may be affected by freeze-thaw procedures. We examined the effect of a single freeze-thaw cycle on 13 nutritional, noncommunicable diseases (NCD), and inflammatory bioanalytes in serum samples. Method Blood samples were collected from 70 subjects centrifuged after 30 minutes and aliquoted immediately. After a baseline analysis of the analytes, the samples were stored at - 70°C for 1 month and reanalyzed for all the parameters. Mean percentage differences between baseline (fresh blood) and freeze-thaw concentrations were calculated using paired sample t -tests and evaluated according to total allowable error (TEa) limits (desirable bias). Results Freeze-thaw concentrations differed significantly ( p < 0.05) from baseline concentrations for soluble transferrin receptor (sTfR) (- 5.49%), vitamin D (- 12.51%), vitamin B12 (- 3.74%), plasma glucose (1.93%), C-reactive protein (CRP) (3.45%), high-density lipoprotein (HDL) (7.98%), and cholesterol (9.76%), but they were within respective TEa limits. Low-density lipoprotein (LDL) (- 0.67%), creatinine (0.94%), albumin (0.87%), total protein (1.00%), ferritin (- 0.58%), and triglycerides (TAG) (2.82%) concentrations remained stable following the freeze-thaw cycle. In conclusion, single freeze-thaw cycle of the biomarkers in serum/plasma samples after storage at - 70°C for 1 month had minimal effect on stability of the studied analytes, and the changes in concentration were within acceptable limit for all analytes.

Multilevel and Multifactorial Interventions to Reduce Alcohol Consumption and Improve ART Adherence and Related Factors Among HIV Positive Men in Mumbai, India.

Alcohol use has a deleterious effect on the health status of persons living with HIV, negatively affecting antiretroviral adherence and increasing the risk of transmission. Alcohol use is not an isolated behavior but intimately linked to stigma and poor psychological status among other factors. This paper utilizes a crossover design to test the efficacy of three multilevel interventions, individual counselling (IC), group intervention (GI) and collective advocacy (CA) for change, among HIV positive males who consume alcohol, treated at five ART Centers in urban Maharashtra, India. While GI shows a significant effect on the largest number of outcome variables, IC through its psychosocial emphasis demonstrated a significant impact over time on stigma and depression, and CA with its emphasis on societal change showed positive impact on stigma and advocacy for self and others. Each of the interventions had variable effects on CD4 count and viral load.Clinical Registration Number: NCT03746457; Clinical Trial.Gov.

RESUMEN: El consumo de alcohol tiene un efecto nocivo en el estado de salud de las personas que viven con VIH, afectando negativamente la adherencia a los antirretrovirales y aumentando el riesgo de transmisión del virus. El consumo de alcohol no es un comportamiento aislado, sino que está íntimamente relacionado con el estigma y el mal estado psicológico, entre otros factores. Este documento utiliza un diseño cruzado para evaluar la eficacia de tres intervenciones: asesoramiento individual, intervención grupal y defensa colectiva para el cambio, entre hombres con VIH que consumen alcohol que reciben tratamiento en cinco centros de terapia antiretroviral en la zona urbana de Maharashtra, India. Si bien la intervención grupal muestra un efecto significativo en el mayor número de variables de interés, el asesoramiento individual a través de su énfasis psicosocial demostró un impacto significativo en el estigma y la depression a largo plazo, y la defensa colectiva con su énfasis en el cambio social mostró un impacto positivo en el estigma y la defensa de sí mismo y otros.

Haemoglobin thresholds to define anaemia in a national sample of healthy children and adolescents aged 1-19 years in India: a population-based study.

BACKGROUND: WHO's haemoglobin cutoffs to define anemia were based on five studies of predominantly White adult populations, done over 50 years ago. Therefore, a general re-examination of the existing haemoglobin cutoffs is warranted for global application, in representative healthy populations of children and adults. Such data are scarce in low-income and middle-income countries; however, a 2019, large-scale, nationally representative survey of children and adolescents aged 0-19 years in India (Comprehensive National Nutrition Survey [CNNS]) offered an opportunity for this re-examination. Using this survey, we aimed to assess the age-specific and sex-specific percentiles of haemoglobin and cutoffs to define anaemia in the CNNS population. METHODS: For this population-based study, we constructed age-specific and sex-specific haemoglobin percentiles from values reported for a defined healthy population in the CNNS, which used rigorous quality control measures during sample collection and in the laboratory analyses. To obtain a healthy population, we excluded participants with iron, folate, vitamin B12, and retinol deficiencies; inflammation; variant haemoglobins (haemoglobin A2 and haemoglobin S); and history of smoking. We considered age-specific and sex-specific 5th percentiles of haemoglobin derived for this healthy population as the study cutoff to define anaemia. We compared these with existing WHO cutoffs to assess significant differences between them at each year of age and sex for quantifying the prevalence of anaemia in the entire CNNS sample. FINDINGS: Between Feb 24, 2016, and Oct 26, 2018, the CNNS survey collected blood samples from 49 486 individuals. 41 210 participants had a haemoglobin value, 8087 of whom were included in our study and comprised the primary analytical sample. Compared with existing WHO cutoffs, the study cutoffs for haemoglobin were lower at all ages, usually by 1-2 g/dL, but more so in children of both sexes aged 1-2 years and in girls aged 10 years or older. Aanemia prevalence with the study cutoffs was 19·2 percentage points lower than with WHO cutoffs in the entire CNNS sample with valid haemoglobin values across all ages and sexes (10·8% with study cutoffs vs 30·0% with WHO cutoffs). INTERPRETATION: These findings support the re-examination of WHO haemoglobin cutoffs to define anaemia. Our haemoglobin reference percentiles, derived from healthy participants in a large representative Indian survey, are suitable for national use in India. Substantial variations in the 5th percentile of haemoglobin values across the 1-19 years age range and between sexes argue against constructing common cutoffs in stratified age groups for convenience. FUNDING: None. TRANSLATIONS: For the Hindi, Punjabi, Tamil and Kannada translations of the abstract see Supplementary Materials section.

Intraindividual double-burden of anthropometric undernutrition and "metabolic obesity" in Indian children: a paradox that needs action.

BACKGROUND: Intra-individual coexistence of anthropometrically defined undernutrition and 'metabolic obesity', characterised by presence of at least one abnormal cardiometabolic risk factor, is rarely investigated in young children and adolescents, particularly in Low-and-Middle-Income-Countries undergoing rapid nutrition transition. METHODS: Prevalence of biomarkers of metabolic obesity was related to anthropometric and socio-demographic characteristics in 5-19 years old participants from the population-based Comprehensive National Nutrition Survey in India (2016-2018). The biomarkers, serum lipid-profile (total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL) and triglycerides), fasting glucose, and glycosylated hemoglobin (HbA1C), and all jointly were analysed in 22567, 23192, 25962 and 19143 participants, respectively. RESULTS: Overall (entire dataset), the prevalence of abnormalities was low (4.3-4.5%) for LDL and TC, intermediate for dysglycemia (10.9-16.1%), and high for HDL and triglycerides (21.7-25.8%). Proportions with ≥1 abnormal metabolic obesity biomarker(s) were 56.2% overall, 54.2% in thin (BMI-for-age < -2 SD) and 59.3% in stunted (height-for-age < -2 SD) participants. Comparable prevalence was evident in mild undernutrition (-1 to -2 SD). Clustering of two borderline abnormalities occurred in one-third, warranting active life-style interventions. Metabolic obesity prevalence increased with BMI-for-age. Among those with metabolic obesity, only 9% were overweight/obese (>1 SD BMI-for-age). Among poor participants, triglyceride, glucose and HDL abnormalities were higher. CONCLUSIONS: A paradoxical, counter-intuitive prevalence of metabolic obesity biomarker(s) exists in over half of anthropometrically undernourished and normal-weight Indian children and adolescents. There is a crucial need for commensurate investments to address overnutrition along with undernutrition. Nutritional status should be characterized through additional reliable biomarkers, instead of anthropometry alone.

Prevalence of low serum zinc concentrations in Indian children and adolescents: findings from the Comprehensive National Nutrition Survey 2016-18.

BACKGROUND: It is thought that there is a high risk of zinc deficiency in India, but there are no representative national estimates. OBJECTIVES: We aimed to evaluate the national and state-level prevalence of low serum zinc concentrations (SZCs) in Indian children from the nationally representative Comprehensive National Nutrition Survey. METHODS: Prevalence of low SZC, adjusted for C-reactive protein, was estimated among preschool (1-4 y; n = 7874) and school-age children (5-9 y; n = 10,430) and adolescents (10-19 y; n = 10,140), using SZC cutoffs defined by the International Zinc Nutrition Consultative Group. RESULTS: Prevalence of low SZC was high among adolescents (31.1%; 95% CI: 29.8%, 32.4%), compared with school-age (15.8%; 95% CI: 15.3%, 16.3%) or preschool children (17.4%; 95% CI: 16.7%, 18.0%). However, stratification of prevalence by fasting status or using an alternative lower SZC cutoff independent of fasting status led to a reduction in prevalence by 3.7% or 7.8% in children <10 y, respectively. The prevalence of low SZC was higher among rural preschool children, those belonging to households with poor socioeconomic status, and those with severe stunting or underweight. Preschool children with diarrhea (22.6%; 95% CI: 20.8%, 24.4%), productive cough (22.7%; 95% CI: 18.5%, 27.5%), or malaria/dengue (38.5%; 95% CI: 29.4%, 48.2%) in the 2 wk preceding the survey had a higher prevalence of low SZC than those without morbidity (16.5%; 95% CI: 15.9%, 17.2%; 17.6%; 95% CI: 16.9%, 18.2%; and 17.5%; 95% CI: 16.8%, 18.1%, respectively). CONCLUSIONS: The national prevalence of low SZC among preschool (17%) or school-age children (16%) was <20%, which is considered the cutoff indicating a problem of public health significance; but there were variations by state and socioeconomic status. In adolescents, however, the prevalence of low SZC was 31%, which warrants further investigation. The association of low SZC with diarrhea in preschool children necessitates better coverage of Zn administration in the management of diarrhea.

A multilevel intervention to reduce stigma among alcohol consuming men living with HIV receiving antiretroviral therapy: findings from a randomized control trial in India.

OBJECTIVE: To examine the effectiveness of a multilevel intervention to reduce HIV stigma among alcohol consuming men living with HIV in India. DESIGN: A crossover randomized controlled trial in four sites. SETTING: Government ART centres (ARTCs) offering core services in the greater Mumbai area. PARTICIPANTS: Seven hundred and fifty two (188 per site) alcohol-consuming male PLHIV on ART were recruited. INTERVENTION: Multilevel intervention to reduce alcohol consumption and promote adherence by addressing stigma, implemented at the individual (individual counselling, IC), group (group intervention, GI) and community levels (collective advocacy, CA) in three distinct sequences over three cycles of 9 months each. MAIN OUTCOME MEASURE: HIV stigma, measured using the 16-item Berger Stigma scale. METHODS: The article examines the effectiveness of the interventions to reduce stigma using Linear Mixed Model regression. RESULTS: At baseline, 57% of participants had moderate-high levels of stigma (scores >40). All three counseling interventions were effective in reducing stigma when delivered individually, in the first cycle (collective advocacy: ßcoeff = -9.71; p < 0.001; group intervention: ßcoeff = -5.22; p < 0.001; individual counselling: ßcoeff = -4.43; p < 0.001). At then end of the second cycle, effects from the first cycle were sustained with no significant change in stigma scores. At the end of the third cycle, the site, which received CA+IC+GI sequence had maximum reduction in stigma scores (ßcoeff = -10.29; p < 0.001), followed by GI+CA+IC (ßcoeff = -8.23, p < 0.001). CONCLUSION: Baseline findings suggest that stigma remains a problem even with experienced patients, despite advances in treatment and adherence. Results of multilevel stigma reduction interventions argue for inclusion in HIV prevention and treatment program.

Modeling HIV Transmission from Sexually Active Alcohol-Consuming Men in ART Programs to Seronegative Wives.

BACKGROUND: The rollout of antiviral therapy in Low and Middle Income Countries (LMICs) has reduced HIV transmission rates at the potential risk of resistant HIV transmission. We sought to predict the risk of wild type and antiviral resistance transmissions in these settings. METHODS: A predictive model utilizing viral load, ART adherence, genital ulcer disease, condom use, and sexual event histories was developed to predict risks of HIV transmission to wives of 233 HIV+ men in 4 antiretroviral treatment centers in Maharashtra, India. RESULTS: ARV Therapy predicted a 5.71-fold reduction in transmissions compared to a model of using condoms alone, with 79.9%, of remaining transmissions resulting in primary ART-resistance. CONCLUSIONS: ART programs reduce transmission of HIV to susceptible partners at a substantial increased risk for transmission of resistant virus. Enhanced vigilance in monitoring adherence, use of barrier protections, and viral load may reduce risks of resistant HIV transmissions in LMIC settings.

Characterisation of the types of anaemia prevalent among children and adolescents aged 1-19 years in India: a population-based study.

BACKGROUND: Anaemia is a serious public health concern in India. However, national estimates for its prevalence are not available for the 5-14 years age group, nor are estimates available for the types of anaemia among children and adolescents (1-19 years). We aimed to assess the prevalence of anaemia among children and adolescents in India and to categorise types of anaemia on the basis of micronutrient deficiencies. METHODS: We assessed the prevalence of anaemia among children (1-4 years and 5-9 years) and adolescents (10-19 years) using nationally representative data from the Comprehensive National Nutrition Survey. Anaemia was classified on the basis of age and sex-specific WHO cutoffs and serum ferritin, soluble transferrin receptor, folate, cyanocobalamin, and C-reactive protein concentrations as iron deficiency anaemia, folate or vitamin B12 deficiency anaemia, dimorphic anaemia (iron deficiency anaemia and folate or vitamin B12 deficiency anaemia), anaemia of other causes (anaemia not classified as iron deficiency anaemia and folate or vitamin B12 deficiency anaemia), and anaemia of inflammation. FINDINGS: We included 26 765 children (11 624 aged 1-4 years and 15 141 aged 5-9 years) and 14 669 adolescents. In the weighted sample, anaemia prevalence was 40·5% (4553 of 11 233) among 1-4 year-olds, 23·4% (3439 of 14 664) among 5-9 year-olds, and 28·4% (4064 of 14 300) among adolescents. Among 2862 children aged 1-4 years, iron deficiency anaemia (1045 [36·5%]) was the most prevalent type, followed by anaemia of other causes (702 [24·5%]), folate or vitamin B12 deficiency anaemia (542 [18·9%]), dimorphic anaemia (387 [13·5%]), and anaemia of inflammation (186 [6·5%]). Among 2261 children aged 5-9 years, anaemia of other causes was the most common (986 [43·6%]), followed by folate or vitamin B12 deficiency anaemia (558 [24·6%]), iron deficiency anaemia (353 [15·6%]), dimorphic anaemia (242 [10·7%]), and anaemia of inflammation (122 [5·4%]). 861 (31·4%) of 2740 adolescents had anaemia of other causes, 703 (25·6%) had folate or vitamin B12 deficiency anaemia, 584 (21·3%) had iron deficiency anaemia, 498 (18·2%) and dimorphic anaemia, and 94 (3·4%) had anaemia of inflammation. INTERPRETATION: Iron deficiency anaemia is the most common form of anaemia among younger children and anaemia of other causes among 5-9-year-old children and adolescents. Folate or vitamin B12 deficiency anaemia accounts for more than a third of anaemia prevalence. Anaemia prevention efforts should focus on strengthening the existing iron and folate supplementation programmes and prevention of folate or vitamin B12 deficiency anaemia.

Viral load outcomes in a cohort of alcohol-consuming people living with HIV receiving antiretroviral therapy in Mumbai, India.

We examined the association between alcohol consumption, adherence and viral load (VL) in a cohort of 940 alcohol-consuming, human immunodeficiency virus (HIV)-positive men receiving antiretroviral therapy in Mumbai. Some of the participants (16.7%) had missed >1 doses in the last four days and 17.6% reported >1 treatment interruptions in the last 12 months; 60.8% of the participants consumed alcohol >2 times/month, 62.8% consumed >3 drinks/typical day and 11.5% reported binge drinking >1 times/month; 76.4% of the participants had VL<200 copies/mL. Higher alcohol consumption was associated with nonadherence (odds ratio [OR]: 1.21; 95% confidence interval [CI]: 1.11-1.31) and treatment interruptions (OR: 1.20; 95% CI: 1.11-1.31). We found no association between alcohol use and VL. There was, however, a significant interaction effect of alcohol use and nonadherence on virological failure (Adjusted Odds Ratio [AOR]: 1.23; 95% CI: 1.03-1.47) implying that alcohol negatively impacts VL outcomes but mediated through adherence. Alcohol use was associated with poor adherence, which in turn was a strong predictor of virological failure.

"It is always better for a man to know his HIV status" - A qualitative study exploring the context, barriers and facilitators of HIV testing among men in Nairobi, Kenya.

HIV testing services are an important component of HIV program and provide an entry point for clinical care for persons newly diagnosed with HIV. Although uptake of HIV testing has increased in Kenya, men are still less likely than women to get tested and access services. There is, however, limited understanding of the context, barriers and facilitators of HIV testing among men in the country. Data are from in-depth interviews with 30 men living with HIV and 8 HIV testing counsellors that were conducted to gain insights on motivations and drivers for HIV testing among men in the city of Nairobi. Men were identified retroactively by examining clinical CD4 registers on early and late diagnosis (e.g. CD4 of ≥500 cells/mm, early diagnosis and <500 cells/mm, late diagnosis). Analysis involved identifying broad themes and generating descriptive codes and categories. Timing for early testing is linked with strong social support systems and agency to test, while cost of testing, choice of facility to test and weak social support systems (especially poor inter-partner relations) resulted in late testing. Minimal discussions occurred prior to testing and whenever there was dialogue it happened with partners or other close relatives. Interrelated barriers at individual, health-care system, and interpersonal levels hindered access to testing services. Specifically, barriers to testing included perceived providers attitudes, facility location and set up, wait time/inconvenient clinic times, low perception of risk, limited HIV knowled ge, stigma, discrimination and fear of having a test. High risk perception, severe illness, awareness of partner's status, confidentiality, quality of services and supplies, flexible/extended opening hours, and pre-and post-test counselling were facilitators. Experiences between early and late testers overlapped though there were minor differences. In order to achieve the desired impact nationally and to attain the 90-90-90 targets, multiple interventions addressing both barriers and facilitators to testing are needed to increase uptake of testing and to link the positive to care.

Effect of temperature and time delay in centrifugation on stability of select biomarkers of nutrition and non-communicable diseases in blood samples.

INTRODUCTION: Preanalytical conditions are critical for blood sample integrity and poses challenge in surveys involving biochemical measurements. A cross sectional study was conducted to assess the stability of select biomarkers at conditions that mimic field situations in surveys. MATERIAL AND METHODS: Blood from 420 volunteers was exposed to 2 - 8 °C, room temperature (RT), 22 - 30 °C and > 30 °C for 30 min, 6 hours, 12 hours and 24 hours prior to centrifugation. After different exposures, whole blood (N = 35) was used to assess stability of haemoglobin, HbA1c and erythrocyte folate; serum (N = 35) for assessing stability of ferritin, C-reactive protein (CRP), vitamins B12, A and D, zinc, soluble transferrin receptor (sTfR), total cholesterol, high density lipoprotein cholesterol (HDL), low density lipoprotein cholesterol (LDL), tryglicerides, albumin, total protein and creatinine; and plasma (N = 35) was used for glucose. The mean % deviation of the analytes was compared with the total change limit (TCL), computed from analytical and intra-individual imprecision. Values that were within the TCL were deemed to be stable. RESULT: Creatinine (mean % deviation 14.6, TCL 5.9), haemoglobin (16.4%, TCL 4.4) and folate (33.6%, TCL 22.6) were unstable after 12 hours at 22-30°C, a temperature at which other analytes were stable. Creatinine was unstable even at RT for 12 hours (mean % deviation: 10.4). Albumin, CRP, glucose, cholesterol, LDL, triglycerides, vitamins B12 and A, sTfR and HbA1c were stable at all studied conditions. CONCLUSION: All analytes other than creatinine, folate and haemoglobin can be reliably estimated in blood samples exposed to 22-30°C for 12 hours in community-based studies.

Cell Phone Counseling Improves Retention of Mothers With HIV Infection in Care and Infant HIV Testing in Kisumu, Kenya: A Randomized Controlled Study.

BACKGROUND: We evaluated the effectiveness of a cell phone counseling intervention to promote retention in care and HIV testing of infants among women with HIV accessing prevention of mother-to-child services in Kisumu, Kenya. METHODS: Between May 2013 and September 2015, we recruited 404 pregnant women with HIV who were between 14 and 36 weeks of gestation and randomly assigned them to the intervention (n=207) or control arm (n=197). Retention was assessed at delivery and at 6 and 14 weeks postpartum. We also measured uptake of infant HIV testing. The intervention comprised a fixed protocol of counselor-delivered phone calls to provide one-to-one need-based support. The number of calls made varied depending on when participants presented for antenatal care services; the maximum number was 42. The control group received routine care. We evaluated retention at 3 time points using the complementary log-log regression model taking into account factors associated with retention and loss to follow-up time. We calculated the incidence rate for HIV transmission among infants and used binary logistic regression to identify predictors of HIV infection among infants. RESULTS: Participants attended on average 63% of the required number of counseling calls during the study period. Retention was higher in the intervention arm than the control arm at delivery (95.2% vs. 77.7%, respectively); 6 weeks postpartum (93.9% vs. 72.9%, respectively); and 14 weeks postpartum (83.3% vs. 66.5%, respectively) (P<.001). The counseling intervention (hazard ratio [HR]=0.29; 95% confidence interval [CI]=0.12, 0.69) and positive health perceptions (HR=0.99; 95% CI=0.98, 1.00) were associated with lower hazards of being lost to follow-up. HIV testing of infants was higher in the intervention than control arm (93% vs. 68%, respectively; P<.001). In total, 9 of 308 (2.9%) infants tested positive for HIV infection (incidence rate=0.39 infections/100 infant-weeks). Medication Possession Ratio (MPR) >90%, used to assess adherence to ART, was associated with lower odds of a positive HIV test among infants (adjusted odds ratio=0.20; 95% CI=0.04, 0.99). Attendance at antenatal and postnatal care visits was higher among participants in the intervention arm than the control arm. CONCLUSIONS: The one-on-one tailored counseling delivered via cell phone was effective in retaining mothers with HIV infection in care and promoting uptake of infant HIV testing and antenatal and postnatal care services. Phone counseling offers a practical approach to reach and retain pregnant women with HIV infection and postpartum mothers in care, but greater emphasis on collection of medications and adherence is required.

The prevalence and determinants of depression among HIV-positive perinatal women receiving antiretroviral therapy in India.

To assess the prevalence and correlates of perinatal depression, 200 HIV-positive pregnant/post-partum women receiving antiretroviral therapy (ART) were interviewed at eight government ART centers in four states across India. 52.5% (105) participants had depressive symptomology (Edinburgh Postnatal Depression Scale score > 13) while 23% of the participants reported thoughts of self-harm; there was no difference between pregnant and postpartum participants. Poor illness perception was associated with depression (AOR, 1.09; 95%CI, 1.05, 1.14); there was no association between adherence and depression in this population.
