Examining the Triple Burden of Malnutrition: Insights from a Community-Based Comprehensive Nutrition Survey among Indigenous Tribal Children (0-19 Years) in the Western Ghats Hills of India.

This article presents findings from a community-based cross-sectional study conducted in Attappadi, Kerala, India, aimed at assessing the prevalence of the triple burden of malnutrition among indigenous children aged 0-19 years. Historically, the indigenous population in Attappadi has faced significant developmental challenges, including high rates of malnutrition, infant mortality, and neonatal mortality. This study revealed alarming rates of undernutrition among children aged 0-59 months, with 40.9% experiencing stunting, 27.4% wasting, and 48.3% being underweight. Adolescent girls also suffered from undernutrition, with 21% classified as underweight and 43.3% experiencing stunting. Surprisingly, overweight or obesity was identified as a nutritional problem, affecting 1.4% of children aged 0-59 months, 4.2% of children aged 5-9 years, and 10.5% of adolescent girls. Additionally, a distressing proportion of young children aged 12-59 months (91.2%) were anaemic, with 50% diagnosed specifically with iron deficiency anaemia (IDA). Nearly all adolescent girls (96.6%) were reportedly suffering from anaemia. Deficiencies in vitamin B12, vitamin D, folate, and vitamin-A were prevalent among 35%, 20%, 16%, and 12% of children aged 12-59 months, respectively. The study underscores the urgent need for comprehensive interventions to address this triple burden of malnutrition. Recommendations include promoting culturally appropriate local food-based solutions, establishing participatory and community-led systems for health and nutrition information dissemination, and strengthening the nutrition surveillance system through village-level health and nutrition workers. By adopting a holistic approach, these interventions can help improve the nutritional status and well-being of the indigenous tribal children in Attappadi.

Large-scale staple food fortification as a complementary strategy to address vitamin and mineral vulnerabilities in India: A critical review.

The slow improvement in micronutrient malnutrition globally and in India warrants a need for scaling-up scientifically proven, cost-effective public health interventions. The present review discusses the potential of staple food fortification as a complementary strategy to tackle micronutrient deficiencies, while addressing the current concerns raised regarding its implementation. The review indicates the below par status of current strategies like dietary diversity and supplementation to address multiple micronutrients deficiencies in India and the need for complementary strategies to tackle this problem. Based on systematic reviews and meta-analysis, global and national evidence has identified staple food fortification as a proven and recognized cost-effective solution to address micronutrient deficiencies. The Government of India has shown a strong leadership to promote this proven intervention. Further, the paper addresses the concern that large-scale staple food fortification (LSFF) may lead to excessive nutrient intakes when delivered together with other interventions, e.g., supplementation, dietary diversity, among the same populations. A key message that emerges from this review is that LSFF is safe with current dietary intake and deficiencies and low coverage of other interventions. Given the current situation of food and nutrition insecurity which the COVID-19 pandemic has further exacerbated, and the critical role that nutrition plays in building immunity, it is even more important that health and nutrition of the population, especially vulnerable age groups, is not only safeguarded but also strengthened. LSFF should be implemented without any further delay to reach the most vulnerable segments of the population to reduce the dietary nutrient gap and prevent micronutrient deficiencies. Effective monitoring and regular dietary surveys will help ensure these interventions are being deployed correctly.

Association between anthropometric criteria and body composition among children aged 6-59 months with severe acute malnutrition: a cross-sectional assessment from India.

A multicentric study is being conducted in which children with severe acute malnutrition (SAM) aged 6-59 months are identified with only weight-for-height z-score (WHZ) < - 3 criteria. The present study aimed to assess associations of anthropometric parameters and body composition parameters, to improve treatment of SAM. We conducted a cross-section assessment using the enrolment data of children who participated in a multi-centric longitudinal controlled study from five Indian states. Fat-free mass (FFM) and fat mass (FM) were determined by bio-electrical impedance analysis (BIA). Six hundred fifty-nine children were enrolled in the study using WHZ < -3 criteria. Available data shows that WHZ, WAZ and BMIZ were significantly associated with FFMI while MUACZ was significantly associated with both FMI and FFMI. Children with both severe wasting and severe stunting had significantly lower FFMI compared to those who were only severely wasted. All forms of anthropometric deficits appear to adversely impact FFM and FM.Trial registrationThe study is registered with Clinical Trial Registration of India (Registration No.: CTRI/2020/09/028013 dated 24/09/2020).

SARS-CoV-2 seroprevalence in the city of Hyderabad, India in early 2021.

Background: COVID-19 emerged as a global pandemic in 2020, spreading rapidly to most parts of the world. The proportion of infected individuals in a population can be reliably estimated via serosurveillance, making it a valuable tool for planning control measures. Our serosurvey study aimed to investigate SARS-CoV-2 seroprevalence in the urban population of Hyderabad at the end of the first wave of infections. Methods: This cross-sectional survey, conducted in January 2021 and including males and females aged 10 years and above, used multi-stage random sampling. 9363 samples were collected from 30 wards distributed over six zones of Hyderabad, and tested for antibodies against SARS-CoV-2 nucleocapsid antigen. Results: Overall seropositivity was 54.2%, ranging from 50% to 60% in most wards. Highest exposure appeared to be among those aged 30-39 and 50-59 years, with women showing greater seropositivity. Seropositivity increased with family size, with only marginal differences among people with varying levels of education. Seroprevalence was significantly lower among smokers. Only 11% of the survey subjects reported any COVID-19 symptoms, while 17% had appeared for COVID-19 testing. Conclusion: Over half the city's population was infected within a year of onset of the pandemic. However, ∼ 46% of people remained susceptible, contributing to subsequent waves of infection.

Effectiveness of community-based treatment programs for treatment of uncomplicated severe acute malnourished children aged 6-59 months using locally produced nutrient dense foods: protocol for a multicentric longitudinal quasi-experimental study.

BACKGROUND: Severe acute malnutrition (SAM) is a major underlying cause of mortality among children. Around one third of the world's acutely malnourished children live in India. The WHO recommends community-based management of acute malnutrition (CMAM) for managing children with SAM. In India, different states are implementing community-based SAM treatment programme, hereinafter called CSAM, using varieties of locally produced nutrient dense food items with different nutrient compositions. The study will assess the effectiveness of these state specific CSAM interventions. METHODS: The longitudinal quasi-experimental study will be undertaken in two purposively selected blocks of one district each in the four intervention states and one comparison state. From each state, 200 SAM children identified using weight-for-length/height z-score (WHZ) < - 3 criteria will be enrolled in the study. Their anthropometric data and skinfold thickness will be taken on admission, at sixth week and at discharge by trained field investigators. Other child details, incidence of morbidity and socio-economic details will be collected on admission. To assess food consumption pattern including consumption of locally produced nutrient dense food supplements, dietary assessment, using 24-h dietary recall will be conducted on admission, at sixth week and at discharge. In addition, body composition parameters will be assessed for a sub-set of children using bio-electrical impedance analysis on admission and at discharge to analyse changes in total body water, fat-free mass, and fat mass. Post discharge, all study participants will be followed up monthly until 6 months. Atleast 10% of the sample will be checked for quality assessment. The study's primary outcome is cure rate defined as children attaining WHZ ≥ -2. Secondary outcomes include mean weight gain, mean length of stay, body composition parameters, relapse and mortality rates. Additionally, process evaluation and cost effectiveness analysis will be conducted. DISCUSSION: There is a shortage of robust evidence regarding the effectiveness of locally produced nutrient dense food supplements provided as part of the CSAM intervention in India. This study will contribute to evidence on effective strategies to manage children with uncomplicated SAM in India. The study protocol has all necessary ethical approvals. Written informed consent will be obtained from caregivers of the children. TRIAL REGISTRATION: The study is registered with Clinical Trial Registration of India (Registration No.: CTRI/2020/09/028013 ) Date of registration 24/09/2020.

Preparedness of primary and secondary health facilities in India to address major noncommunicable diseases: results of a National Noncommunicable Disease Monitoring Survey (NNMS).

BACKGROUND: The monitoring framework for evaluating health system response to noncommunicable diseases (NCDs) include indicators to assess availability of affordable basic technologies and essential medicines to treat them in both public and private primary care facilities. The Government of India launched the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular diseases and Stroke (NPCDCS) in 2010 to strengthen health systems. We assessed availability of trained human resources, essential medicines and technologies for diabetes, cardiovascular and chronic respiratory diseases as one of the components of the National Noncommunicable Disease Monitoring Survey (NNMS - 2017-18). METHODS: NNMS was a cross-sectional survey. Health facility survey component covered three public [Primary health centre (PHC), Community health centre (CHC) and District hospital (DH)] and one private primary in each of the 600 primary sampling units (PSUs) selected by stratified multistage random sampling to be nationally representative. Survey teams interviewed medical officers, laboratory technicians, and pharmacists using an adapted World Health Organization (WHO) - Service Availability and Readiness Assessment (SARA) tool on handhelds with Open Data Kit (ODK) technology. List of essential medicines and technology was according to WHO - Package of Essential Medicines and Technologies for NCDs (PEN) and NPCDCS guidelines for primary and secondary facilities, respectively. Availability was defined as reported to be generally available within facility premises. RESULTS: Total of 537 public and 512 private primary facilities, 386 CHCs and 334 DHs across India were covered. NPCDCS was being implemented in 72.8% of CHCs and 86.8% of DHs. All essential technologies and medicines available to manage three NCDs in primary care varied between 1.1% (95% CI; 0.3-3.3) in rural public to 9.0% (95% CI; 6.2-13.0) in urban private facilities. In NPCDCS implementing districts, 0.4% of CHCs and 14.5% of the DHs were fully equipped. DHs were well staffed, CHCs had deficits in physiotherapist and specialist positions, whereas PHCs reported shortage of nurse-midwives and health assistants. Training under NPCDCS was uniformly poor across all facilities. CONCLUSION: Both private and public primary care facilities and public secondary facilities are currently not adequately prepared to comprehensively address the burden of NCDs in India.

Baseline risk factor prevalence among adolescents aged 15-17 years old: findings from National Non-communicable Disease Monitoring Survey (NNMS) of India.

OBJECTIVE: To generate national estimates of key non-communicable disease (NCD) risk factors for adolescents (15-17 years) identified in the National NCD Monitoring Framework and, study the knowledge, attitudes and practices towards NCD risk behaviours among school-going adolescents. DESIGN AND SETTING: A community-based, national, cross-sectional survey conducted during 2017-2018. The survey was coordinated by the Indian Council of Medical Research-National Centre for Disease Informatics and Research with 10 reputed implementing research institutes/organisations across India in urban and rural areas. PARTICIPANTS: A multistage sampling design was adopted covering ages between 15 and 69 years-adolescents (15-17 years) and adults (18-69 years). The sample included 12 000 households drawn from 600 primary sampling units. All available adolescents (15-17 years) from the selected households were included in the survey. MAIN OUTCOME MEASURES: Key NCD risk factors for adolescents (15-17 years)-current tobacco and alcohol use, dietary behaviours, insufficient physical activity, overweight and obesity. RESULTS: Overall, 1402 households and 1531 adolescents completed the survey. Prevalence of current daily use of tobacco was 3.1% (95% CI: 2.0% to 4.7%), 25.2% (95% CI: 22.2% to 28.5%) adolescents showed insufficient levels of physical activity, 6.2% (95% CI: 4.9% to 7.9%) were overweight and 1.8% (95% CI: 1.0% to 2.9%) were obese. Two-thirds reported being imparted health education on NCD risk factors in their schools/colleges. CONCLUSION: The survey provides baseline data on NCD-related key risk factors among 15-17 years in India. These national-level data fill information gaps for this age group and help assess India's progress towards NCD targets set for 2025 comprehensively. Though the prevalence of select risk factors is much lower than in many developed countries, this study offers national evidence for revisiting and framing appropriate policies, strategies for prevention and control of NCDs in younger age groups.

National noncommunicable disease monitoring survey (NNMS) in India: Estimating risk factor prevalence in adult population.

BACKGROUND: The primary objective of National NCD monitoring survey (NNMS) was to generate national-level estimates of key NCD indicators identified in the national NCD monitoring framework. This paper describes survey study protocol and prevalence of risk factors among adults (18-69 years). MATERIALS AND METHODS: NNMS was a national level cross-sectional survey conducted during 2017-18. The estimated sample size was 12,000 households from 600 primary sampling units. One adult (18-69 years) per household was selected using the World Health Organization-KISH grid. The study tools were adapted from WHO-STEPwise approach to NCD risk factor surveillance, IDSP-NCD risk factor survey and WHO-Global adult tobacco survey. Total of 8/10 indicators of adult NCD risk factors according to national NCD disease monitoring framework was studied. This survey for the first time estimated dietary intake of salt intake of population at a national level from spot urine samples. RESULTS: Total of 11139 households and 10659 adults completed the survey. Prevalence of tobacco and alcohol use was 32.8% (95% CI: 30.8-35.0) and 15.9% (95% CI: 14.2-17.7) respectively. More than one-third adults were physically inactive [41.3% (95% CI: 39.4-43.3)], majority [98.4% (95% CI: 97.8-98.8)] consumed less than 5 servings of fruits and / or vegetables per day and mean salt intake was 8 g/day (95% CI: 7.8-8.2). Proportion with raised blood pressure and raised blood glucose were 28.5% (95% CI: 27.0-30.1) and 9.3% (95% CI: 8.3-10.5) respectively. 12.8% (95% CI: 11.2-14.5) of adults (40-69 years) had ten-year CVD risk of ≥30% or with existing CVD. CONCLUSION: NNMS was the first comprehensive national survey providing relevant data to assess India's progress towards targets in National NCD monitoring framework and NCD Action Plan. Established methodology and findings from survey would contribute to plan future state-based surveys and also frame policies for prevention and control of NCDs.

Prolonged consumption of grass pea (64 g/Cu/day) along with millets and other cereals causes no neurolathyrism.

Objective: To assess the safe limit of L. sativus (grass pea) consumption along with cereals and millets.Methods: A community-based cross-sectional study was undertaken in three districts (Bilaspur, Durg and Raipur) of Chhattisgarh state. A total of 1500 households (HHs) were surveyed. A total of 360 split grass pea (SGP) samples were collected from all three districts for ?-ODAP analysis. Clinical examination was carried out for symptoms of neurolathyrism. Diet survey was done on 5769 HHs by 24hr recall method. Mean intake of different foods and nutrients were calculated. Based on food frequency questionnaire, HHs were separated into daily consumers of SGP along with its quantity consumed and that never consumed SGP.Results: The study revealed that 30 daily consuming and 89 never consuming HHs, in all the three districts. Daily SGP was consumed at an average of 64 g/Cu/day along with millets, cereals and vegetables. Whereas among the never consumers of SGP, mean intake of vegetables was higher than recommended intakes in addition to pulses. The average ?-ODAP content in SGP was 0.630 g%. The nutritional status of children <5 years and the adults was not significantly different between the daily SGP consumers and never consumers. Households in all the three districts, who consumed the SGP recipes, followed the method of washing, boiling, draining the excess water and cooking the pulse.Discussion: There were no adverse effects observed among daily consumers of grass pea (64 g/CU/day) along with millets, cereals and vegetables.

Infant and young child feeding practices, sociodemographic factors and their association with nutritional status of children aged <3 years in India: findings of the National Nutrition Monitoring Bureau survey, 2011-2012.

OBJECTIVE: To study infant and young child feeding (IYCF) practices and their association with nutritional status among young children. DESIGN: A community-based, cross-sectional study was carried out in ten states of India, using a multistage random sampling method. Anthropometric measurements such as length/height and weight were conducted and nutritional assessment was done using the WHO child growth standards. SETTING: National Nutrition Monitoring Bureau survey, 2011-2012.ParticipantsChildren aged <3 years and their mothers. RESULTS: Only 36 % of infants received breast-feeding within an hour of birth and 50 % were exclusively breast-fed up to 6 months. Prevalence of underweight, stunting and wasting was 38, 41 and 22 %, respectively. The chance of undernutrition among <3-year-old children was significantly higher among those from scheduled caste/scheduled tribe communities, the lowest-income group, with illiterate mothers and lack of sanitary latrine. Among infants, the chance of undernutrition was significantly higher among low-birth-weight babies, and among children whose mother had not consumed iron-folic acid tablets during pregnancy. Immunization practices and minimum dietary diversity were observed to be associated with undernutrition among 12-23-month-old children. CONCLUSIONS: Undernutrition is still an important public health problem in India and observed to be associated with low socio-economic status, illiteracy of mother, low birth weight and dietary diversity. Improving socio-economic and literacy status of mothers can help in improving maternal nutrition during pregnancy and thus low birth weight. Also, improving knowledge of mothers about IYCF practices will help in improving children's nutritional status.

Current scenario of consumption of Lathyrus sativus and lathyrism in three districts of Chhattisgarh State, India.

Lathyrism is a disease caused by excessive consumption of grass pea, Lathyrus sativus especially under conditions of severe drought. Grass pea contains 3-N-oxalyl-L-2, 3-diaminopropanoic acid (ß-ODAP) a putative neurotoxin which acts through excitatory mechanism causing Neurolathyrism. Due to awareness of the disease, availability of food and levels of consumption of L. sativus there is reduction in lathyrism cases where higher consumption of L. sativus is reported in India. The present study was undertaken with the objective to assess the current scenario of consumption of L. sativus, incidence of cases of lathyrism, ß-ODAP, protein and amino acids content in L. sativus pulse collected from three districts (Bilaspur, Durg and Raipur) of Chattisgarh state. For this purpose, a total of 17,755 (13,129 rural and 4626 urban) individuals from 151 villages and 60 wards from urban area were covered for clinical examination. Out of total 5769 households (HHs) covered during the survey, 1602 HHs were cultivators, 1791 HHs non-cultivators and 2376 agricultural and other labourers. A one day 24-hour re-call diet survey was carried out in 5758 HHs (4549 rural and 1209 urban). A total of 360 split grass pea (SGP) samples were collected to estimate ß-ODAP, protein and amino acids content. Results of the study revealed that an average consumption of SGP was 20.9 gm/CU/day in Bilaspur and no consumption was reported among urban population of Raipur. Only nine old cases of lathyrism were found during the study. The mean ß-ODAP content in SGP was 0.63 ±â€¯0.14, 0.65 ±â€¯0.13 and 0.65 ±â€¯0.14 gm/100 gm, whereas the protein content was 27.0 ±â€¯2.39, 27.0 ±â€¯1.99 and 26.7 ±â€¯1.90 gm/100 gm in samples collected from Bilaspur, Durg and Raipur districts respectively. Arginine content was high in SGP and sulphur containing amino acids (cysteine and methionine) were less than other amino acids. In conclusion, the consumption of SGP was lower in these three districts with lower ß-ODAP content than earlier reports, thus the lower prevalence of lathyrism in the districts surveyed.

An unusual case of insecticide poisoning presenting as acute kidney injury.

Poisoning due to insecticides such as organophosphorus and super vasmol presenting as acute kidney injury (AKI) is well-reported. Poisoning due to fipronil (phenylpyrazole) is known to present with mild neurological and dermatological complaints. However, fipronil poisoning presenting as AKI and hepatic dysfunction is not known. Herein, we are presenting a case of fipronil poisoning presenting with severe AKI.

Trends in nutritional status and nutrient intakes and correlates of overweight/obesity among rural adult women (≥18-60 years) in India: National Nutrition Monitoring Bureau (NNMB) national surveys.

OBJECTIVE: To assess trends in nutrient intakes and nutritional status of rural adult women (≥18-60 years) and the association of sociodemographic characteristics with overweight/obesity. DESIGN: Community-based cross-sectional studies carried out during 1975-79 to 2011-12 by the National Nutrition Monitoring Bureau (NNMB) were used. Anthropometric measurements such as height, weight and waist circumference, carried out during the surveys, were used. Association and logistic regression analyses between sociodemographic characteristics and overweight/obesity and abdominal obesity were conducted using a complex samples procedure. SETTING: Ten NNMB states of India. SUBJECTS: Non-pregnant and non-lactating rural women aged ≥18-60 years covered during the above periods from ten states in India. RESULTS: The prevalence of chronic energy deficiency has declined from 52 % during 1975-79 to 34 % during 2011-12, while that of overweight/obesity has increased from 7 % to 24 % during the same period. Median intakes of most of the nutrients have increased over the same period, although they were below recommended levels. The chance of overweight/obesity and abdominal obesity was significantly (P<0·01) higher among women aged 40-60 years, those belonging to Christian religion and other backward communities, women living in pucca houses, literate women, women engaged in service and business, and those having higher per capita income. CONCLUSIONS: Prevalence of chronic energy deficiency has declined significantly; however, overweight/obesity has increased during the same period. This increase in overweight/obesity may be attributed to increased consumption of fatty foods, sedentary lifestyle and improved socio-economic status. There is a need to educate the community about regular physical exercise, low intakes of fats and oils, and a balanced diet.

Status of Vitamin B12 and Folate among the Urban Adult Population in South India.

BACKGROUND: Deficiency of vitamin B12 (B12) and folate (FA) leads to a wide spectrum of disorders that affect all age groups. However, reports on B12 and FA status in healthy adults in India are limited. Hence, we determined the plasma levels and dietary intake of B12 and FA in the adult population. METHODS: We conducted a community-based cross-sectional study in an urban setup among 630 apparently healthy adults distributed into 3 age groups: 21-40, 41-60 and >60 years. Plasma concentrations of B12 and FA were analyzed by radio immunoassay and dietary intake by 24-hour recall method. RESULTS: The overall prevalence of FA deficiency was 12%, but there was no significant difference in plasma FA concentrations among the groups. While the overall prevalence of B12 deficiency was 35%, it was significantly higher in the 21-40 (44%) and 41-60 age groups (40%) when compared with the >60 group (30%). B12 deficiency was higher in vegetarians (54%) compared to those consuming mixed diet (31%), and the reverse was the case with FA. However, the dietary intakes of FA and B12 were not significantly different among the groups. CONCLUSIONS: These results indicate a higher prevalence of B12 deficiency in apparently healthy adults in an urban setup.

Socio-economic & demographic determinants of hypertension & knowledge, practices & risk behaviour of tribals in India.

BACKGROUND & OBJECTIVES: An increase in prevalence of hypertension has been observed in all ethnic groups in India. The objective of the present study was to estimate prevalence and determinants of hypertension among tribals and their awareness, treatment practices and risk behaviours in nine States of India. METHODS: A community based cross-sectional study adopting multistage random sampling procedure was carried out. About 120 Integrated Tribal Development Authority villages were selected randomly from each State. From each village, 40 households were covered randomly. All men and women ≥ 20 yr of age in the selected households were included for various investigations. RESULTS: A total of 21141 men and 26260 women participated in the study. The prevalence of hypertension after age adjustment was 27.1 and 26.4 per cent among men and women, respectively. It was higher in the s0 tates of Odisha (50-54.4%) and Kerala (36.7-45%) and lowest in Gujarat (7-11.5%). The risk of hypertension was 6-8 times higher in elderly people and 2-3 times in 35-59 yr compared with 20-34 yr. Only <10 per cent of men and women were known hypertensives and more than half on treatment (55-68%). Men with general and abdominal obesity were at 1.69 (CI: 1.43-2.01) and 2.42 (CI: 2.01-2.91) times higher risk of hypertension, respectively, while it was 2.03 (CI=1.77-2.33) and 2.35 (CI 2.12-2.60) times higher in women. Those using tobacco and consuming alcohol were at a higher risk of hypertension compared with the non users. INTERPRETATION & CONCLUSIONS: The study revealed high prevalence of hypertension among tribals in India. Age, literacy, physical activity, consumption of tobacco, alcohol and obesity were significantly associated with hypertension. Awareness and knowledge about hypertension and health seeking behaviour were low. Appropriate intervention strategies need to be adopted to increase awareness and treatment practices of hypertension among tribals.

Prevalence of undernutrition, its determinants, and seasonal variation among tribal preschool children of Odisha state, India.

A community-based cross-sectional study was undertaken in the tribal areas of Odisha state, India, covering 1951 preschool children to assess their nutritional status in terms of underweight, stunting, and wasting; its correlates; and seasonal variation in nutritional status. χ(2) Test, one-way analysis of variance, and unadjusted and adjusted odds ratios were used for data analysis. The prevalence of underweight, stunting, and wasting was 58%, 65%, and 20%, respectively. The risk of underweight and stunting was, respectively, 1.9 and 2.4 times higher among children of illiterate mothers, whereas underweight and wasting was 1.4 times higher among children who had morbidities during the preceding fortnight. The prevalence of undernutrition was significantly (P < .01) higher during monsoon as compared with winter season. Undernutrition is an important public health problem and is associated with literacy of mother, morbidity, and season. Thus, improving socioeconomic condition, literacy, and sanitation along with insuring food security during monsoon season might improve nutritional status.

Prevalence of hypertension, its correlates and awareness among adult tribal population of Kerala state, India.

BACKGROUND: Increasing prevalence of hypertension is a public health problem in India. AIMS: To study prevalence, correlates, and awareness of hypertension among tribal adult population in Kerala. SETTING AND DESIGN: A community-based, cross-sectional study was carried out in tribal areas of Kerala by adopting multistage random sampling procedure. MATERIALS AND METHODS: Data was collected on socio-demographic and behavioral factors, and anthropometric measurements were carried out. Body mass index (BMI) was categorized using the classification recommended for Asians. Waist circumference ≥ 90 cm for men and ≥ 80 cm for women was used cut off for defining an abdominal obesity. Bivariate and multivariate analysis was carried out to study association of hypertension with socio-demographic variables, personal habits, and obesity. RESULTS: A total of 4,193 adults (men 1,891, women: 2,302) of ≥ 20 years of age were covered. The overall prevalence of hypertension was 40% (n=1671). The prevalence of hypertension increases with increase in age among both the genders. Regression analysis showed that the risk of hypertension was significantly (P<0.001) lower among educated and among higher socio-economic status group. Sedentary activity had 1.3 times (CI=1.09-1.60) and alcohol consumption had 1.4 (CI=1.17-1.73) times higher risk of hypertension. The risk of hypertension was 1.7 times higher among overweight/obese subjects. Overall, only 10% (n=164) of the adult population was aware of hypertension status, and about 8% (n=129) were on regular treatment. CONCLUSION: It was observed that the prevalence of hypertension was higher among tribal adult population of Kerala and was associated with age, gender, education, HHs wealth index, physical inactivity, alcohol consumption, and overweight/obesity.

Prevalence and determinants of undernutrition and its trends among pre-school tribal children of Maharashtra State, India.

A community-based cross-sectional study carried out in tribal areas of Maharashtra covering 1751 pre-school children to assess nutritional status. Nutritional status was assessed using new WHO Growth Standards. Household wealth index was constructed using principle component analysis. The prevalence of underweight, stunting and wasting was 64, 61 and 29%, respectively. There was a significant (p < 0.05) reduction in the prevalence of underweight and stunting over two time periods (1999 and 2008). Logistic regression showed that the risk of underweight was 1.7 times higher among children of illiterate mothers and those suffering from morbidities, while stunting was 1.4 times higher among children belonging to lowest and middle household's wealth indexes. Undernutrition is a public health problem and is associated with literacy of mother, household wealth index and morbidities. Therefore, improving socio-economic condition along with literacy of mothers and preventing infections through personal hygiene might help in improving the nutritional status of children.

Correlation of Fat Mass Index and Fat-Free Mass Index with percentage body fat and their association with hypertension among urban South Indian adult men and women.

BACKGROUND: The assessment of Fat Mass and Fat-Free Mass indices provides valuable information about changes in body composition. AIM: To identify cut-off points for Fat Mass Index (FMI) to predict an upper limit of percentage body fat of men (25%) and women (30%) for defining obesity and its association with hypertension. SUBJECTS AND METHODS: A total of 436 men and 596 women were included in the study. Fat mass was calculated using skin-fold measurements. FMI cut-off points to predict an upper limit of percentage body fat of 25% (men) and 30% (women) for defining obesity were assessed using Receiver Operating Characteristic (ROC) curve analysis. RESULTS: ROC curve analysis indicated that the level of FMI was 6.59 kg/m(2) in men and 6.64 kg/m(2) in women at 25% and 30% body fat, respectively. Risk estimation for hypertension with FMI indicated high risk of hypertension in men (OR: 3.4, CI: 2.1-5.5) as well as in women (OR: 5.3, CI: 2.3-12.4). CONCLUSION: The level of FMI was 6.6 kg/m(2) in men and women predicted at upper limits of 25% and 30% body fat, respectively, for defining obesity.
