ABSTRACT
Introduction: Malnutrition is a common complication among HIV-infected children. HIV impairs the immune system, making the body vulnerable to various infections. Infections leads to malnutrition which further contributes to a weakened immune system making a vicious cycle. This leads to a rapid progression to AIDS.
Objectives: To assess the burden of malnutrition and to know its effect on immune status of HIV infected children attending Anti-Retro viral Therapy (ART) Centre.
Methodology: The study was conducted among HIV positive children aged 0-14 years, attending ART Centre of Belagavi Institute of Medical Sciences (BIMS) Hospital, Belagavi. Anthropometric measurements and CD4 counts were recorded. An- thropometric indicators were expressed in Z-scores. Three types of malnutrition were defined: acute malnutrition (WHZ/BAZ < -2 SD and HAZ 2 -2SD), chronic malnutrition (HAZ < -2 SD and WHZ/BAZ 2 -2 SD) and mixed malnutrition (WHZ/BAZ < -2 SD and HAZ < -2SD).
Results: The study included 180 HIV infected children (112 boys, 68 girls). The prevalence of malnutrition was 78.3%. Acute, chronic and mixed malnutrition was seen in 17 (9.4%), 106 (58.9%), 18 (10.0%) of the study participants respectively. Immu- nodeficiency was seen in 42% of them. The presence of malnutrition in the study participants was significantly associated with immunodeficiency.
Conclusion: There was high prevalence of malnutrition among the HIV infected children. HIV acts as an independent risk fac- tor for malnutrition. Malnutrition should be treated and prevented to ensure optimal response to ART and reduce early mortality.

INTRODUCTION AIDS related illnesses.'By 2015, India has 21.17 lakh people living with HIV with adult prevalence (15-49yrs) of 0.26%. In Karnataka there were 1, 99,060 people living with HIV with adult prevalence of 0.45%. In India 1,38,456 children
(<15yr) were living with HIV, with prevalence of 6.54% and
According to world health organization (WHO), by 2017 an estimated 36.9 million people were living with Human Im- munodeficiency Virus(HIV) worldwide, 1.8 million People
were newly infected with HIV and 9, 40,000 people died from Acquired Immune Deficiency Syndrome (AIDS) re- lated illnesses. Children (<15yr) living with HIV accounts for an estimated 1.8 million of which 1, 80,000 children were newly infected with HIV and 1, 10,000 children died due to
7,526 deaths due to AIDS related illnesses.”
Infants and young children who have been infected through the route of mother to child transmission (perinatal infection) have very high loads of HIV virus in their body. Furthermore,

the body’s response against the HIV virus is inadequate be- cause the immune system is still immature and developing. Thus, these children progress rapidly towards severe symp- tomatic disease or AIDS. HIV impairs the immune system, making the body vulnerable to various infections. In order to cope with HIV and other infections, the need for energy and other nutrients is increased. If these increased needs are not met, malnutrition sets in. Malnutrition contributes to a weakened immune system, which worsens the effect of HIV. This leads to a rapid progression to AIDS. Thus forming a vi- cious cycle.’ Even at the early stage of HIV when the effects may not be visible (asymptomatic phase), HIV infection has a substantial impact on the nutritionalstatus of infected peo- ple due to poor food intake as a result of poor appetite and difficulty eating, intestinalmalabsorption because of chronic diarrhea and HIV caused intestinal cell damage, metabolic changes and increased nutrient requirements related to op- portunistic infections (OIs).* HIV infected children remain nutritionally challenged due to low socio-economic status, orphan hood, food insecurity, poor dietary patterns, low ma- ternal education and other specific health related factors. ©! Children also differ from adults as they have higher rate of viral replication hence high viral load and higher rate of CD4 cell destruction.Protein—energy /calorie malnutrition (PEM) is the commonest cause of immuno-deficiency.* Hence this study was undertaken to assess the burden of malnutrition and its effect on immune status of HIV positive children.
MATERIALS & METHODS
This Hospital based observational study was conducted among HIV positive children aged 0-14 years of age who were on Anti-Retro viral Therapy (ART) attending ART Centre of Belagavi Institute of Medical Sciences (BIMS) Hospital, Belagavi for a period of 12months from January 2015 to December 2015.
SELECTION CRITERIA: (a) Inclusion Criteria:
¢ Confirmed case of HIV infection e Age 0-14years e On Anti-Retroviral Therapy (ART)
(b) Exclusion criteria:
e Parents/ guardians of children not willing to partici- pate in the study.
e Children whose complete details were not known/ could not be accessed.
Sample size was estimated by considering the prevalence of malnutrition among HIV infected children.® Calculated sam- ple size was 154. However, the present study included 180
individuals. Children attending ART Centre of BIMS Hos- pital, Belagavi who fulfilled selection criteria were studied. Each child had a unique ART number. Hence repetition was avoided and every child was studied only once during the study period.
After obtaining consent, data was collected from parents or guardians of study participants by using a structured, pre- validated, questionnaire. Information regarding Socio-de- mographic profile (date of birth, religion, education, month- ly income, and parental history), immunization history, and disease (HIV) related history was collected. Anthropometric measurements like height and weight of the child was taken. Immunological profile (Recent CD4 count) of the child was collected from case records of ART Centre.
To define malnutrition, several anthropometric indicators were used according to WHO definitions: Height-for-Age, for children up to 19 years, Weight-for-Height for children < 5 years and Body Mass Index (BMI)-for-Age for children > 5 years, and Weight-for-age, for children < 10 years. These indicators are standardized using Z-scores, which quantify how many Standard Deviations (SDs) child’s weight and height is from the median value of a child of the same age and sex, in a reference population. For this analysis, we used the 2006 WHO growth charts for children <5, and the 2007 WHO growth charts for children > 5.” Each indicator allows to define three types of malnutrition: wasting when Weight- for-Height Z score (WHZ) or BMI-for-Age Z-score (BAZ) <-2 SD, stunting when Height-for-Age Z-score (HAZ) < -2 SD, and underweight when Weight-for-Age Z-score (WAZ) < -2 SD. A child is defined as moderately malnourished if the Z score is between -3 and -2 SD, and severely malnourished if the Z-score < -3 SD. For those children who knew exact date of birth, Z-scores were calculated using WHO Anthro Software (version 3.2.2, January 2011) and WHO Anthro Plus. In this study, we combined these indicators to define three categories of malnutrition: (1) acute malnutrition de- fined by WHZ or BAZ<-2 SD and HAZ> -2 SD; (2) chronic malnutrition defined by WHZ/BAZ > -2 SD and HAZ< -2 SD, and (3) mixed malnutrition as WHZ/ BAZ < -2 SD and HAZ < -2 SD. WAZ was not used here. [6
WHO Immunological classification® was used to categorize immune status of the study participants. CD4+ count >500 was considered to be normal. Those with CD4+ count 350- 499, 200-349, <200 or <15% were categorized to have mild, moderate and severe immunodeficiency respectively.
Statistical analysis was done using Microsoft excel sheet 2007 and SPSS version 22. The categorical data was ex- pressed in terms of rates, ratios and percentages while con- tinuous data was expressed as mean + standard deviation. Chi square test was used to test the association between dif- ferent qualitative variables. At 95% CI a probability value (p value) of < 0.05 was considered as statistically significant.

Ethical Clearance:
The study was approved from Institutional Ethics Commit- tee BIMS, Belagavi. Permission to conduct the study was obtained from head of the institute and Nodal Officer and Medical Officer of Anti-Retroviral Therapy (ART) Centre of Belagavi Institute of Medical Sciences (BIMS) Hospital, Belagavi.
RESULTS
This present study included 180 HIV infected children of which boys were 112 (62.2%) and girls were 68 (37.8%) with boys to Girls ratio of 1.65:1. The study participants were of the age group 0-14 years. The mean age (in years) of study participants was 11.11+ 2.87 SD. Table 1 describes the socio-demographic profile of the study participants. In this study, majority of the study participants 167 (92.7%) were Hindu’s. More than half of the study participants 115(63.9%) belonged to rural area. More than half of them 101 (56.1%) were doing primary education. More than 3/4th of study par- ticipants 143 (79.4%) belonged to class 5 socioeconomic sta- tus according to modified BG Prasad classification. Preva- lence of orphan hood was 73.3% (132).
Table 2 describes the demographic and HIV infection related parameters of the parents of the study participants. Majority of the fathers i.e., 57 (31.7%) and mothers 100 (55.6%) of the study participants were illiterates. Majority of the fathers 69 (38.3%) were farmers by occupation followed by drivers 32 (17.8%) and laborers 35 (19.4%). Half of the mothers 92 (51.1%) were house wives by occupation followed by farm- ers 45 (25.0%) and laborers 25 (13.9%) etc. Only 70% of the fathers HIV status was known, of which 117 (65.0%) were positive and 9 (5.0%) of them were negative. Whereas 85% of the mothers HIV status was known, of which 148 (82.2%) of them were positive and 5 (2.8%) of them were negative. Among HIV positives, 42 (23.3%) of the fathers and 107 (59.4%) of the mothers were on ART.
The prevalence of malnutrition in this study was 78.4%. Under nutrition was more common in boys 89 (63.1%) than girls 52 (36.9%). Among children aged 0-10years old, under- weight was seen in 17 (27.8%) of them. Among children aged 0-14 years old, wasting was seen in 35 (19.4%) and stunting was seen in 124 (68.8%) of them as shown in table 3. Acute, chronic and mixed malnutrition was seen in 17 (9.4%), 106 (58.9%), 18 (10.0%) of the study participants respectively as shown in graph 1. The mean CD4 count of the study partici- pants was 735.14532.2 cells/mm3. According to WHO im- munological classification, 105 (58.3%) of the study partici- pants did not have immunodeficiency. Whereas 28 (15.6%) of them had mild, 26 (14.4%) of them had advanced and 21 (11.7%) of them had severe immunodeficiency as shown in graph 2. There was significant association between malnutri-
tion and presence of immunodeficiency among stud partici- pants as mentioned in table 4.
DISCUSSION
This present study included HIV infected children of age 0-14years old. Of which, more than half of them 66.2% were of 11-14years of age group. Similar finding was seen in a study by Meenal Gupta et.al.? The mean age (in years) of study participants was 11.114 2.87 SD. Which was slightly high compared to other studies!®!!. Boys to Girls ratio was 1.65:1 which was similar to other studies.*!*""* More than half of the study participants (63.9%) belonged to rural area. This was the same as seen in a study done in Punjab’ and sev- eral other studies.*'* More than 3/4th of study participants (79.4%) belonged to class V socioeconomic status, whereas several other studies*>'° showed that majority of them were in Class IV. The prevalence of orphan-hood was 73.3%, which was very high compared to studies conducted in Ni- geria (36.4%)! and North India (39.15%).!!
The prevalence of under nutrition was 78.3%. Nearly same result was seen in a study done in Nigeria.'S Whereas this was very high compared to studies done in Cotonou (27.1%) (61 and Central and West Africa (42%).° More than half of the study participants (58.9%) had chronic malnutrition fol- lowed by mixed malnutrition (10.0%) and acute malnutrition (9.4%). Similar findings were seen in studies conducted in Central and West Africa’ and in India.'’ Majority of the chil- dren had stunting (68.8%) followed by underweight (27.8%) and wasting (19.4%). Similar results were seen in several studies.*!5
Majority of the study participants had mild immunodefi- ciency (15.6%) followed by advanced (14.4%) and severe immunodeficiency (11.7%). Similar result was seen in many studies.*!*!6 Whereas in few other studies®*!? majority of the study participants had severe immunodeficiency. The mean CD4 count of the study participants was 735.1+532.2 cells/ mm?. Similar result was seen in few studies done in North India” and Bengaluru.”!
CONCLUSION AND LIMITATIONS:
There was high prevalence of malnutrition among the HIV infected children. HIV acts as an independent risk factor for malnutrition. Malnutrition should be targeted to ensure opti- mal response to ART and reduce early mortality.
