Malaria Vector Bionomics: Countrywide Surveillance Study on Implications for Malaria Elimination in India.

BACKGROUND: The biological characteristics of mosquito vectors vary, impacting their response to control measures. Thus, having up-to-date information on vector bionomics is essential to maintain the effectiveness of existing control strategies and tools, particularly as India aims for malaria elimination by 2030. OBJECTIVE: This study aims to assess the proportions of vector species resting indoors and outdoors, determine their preference for host biting/feeding, identify transmission sites, and evaluate the susceptibility of vectors to insecticides used in public health programs. METHODS: Mosquito collections were conducted in 13 districts across 8 Indian states from 2017 to 2020 using various methods to estimate their densities. Following morphological identification in the field, sibling species of Anopheles mosquitoes were identified molecularly using polymerase chain reaction (PCR)-specific alleles. Plasmodium falciparum and Plasmodium vivax infections in the vectors were detected using enzyme-linked immunosorbent assay (ELISA) and PCR assays. In addition, we assessed the insecticide susceptibility status of primary malaria vectors following the World Health Organization (WHO) protocol. RESULTS: Anopheles culicifacies, a primary malaria vector, was collected (with a man-hour density ranging from 3.1 to 15.9) from all states of India except those in the northeastern region. Anopheles fluviatilis, another primary vector, was collected from the states of Madhya Pradesh, Maharashtra, Karnataka, and Odisha. In Haryana and Karnataka, An. culicifacies sibling species A predominated, whereas species C and E were predominant in Madhya Pradesh and Maharashtra. An. culicifacies displayed mainly endophilic behavior across all states, except in Madhya Pradesh, where the proportion of semigravid and gravid mosquitoes was nearly half of that of unfed mosquitoes. The human blood index of An. culicifacies ranged from 0.001 to 0.220 across all study sites. The sporozoite rate of An. culicifacies ranged from 0.06 to 4.24, except in Madhya Pradesh, where none of the vector mosquitoes were found to be infected with the Plasmodium parasite. In the study area, An. culicifacies exhibited resistance to DDT (dichlorodiphenyltrichloroethane; with <39% mortality). Moreover, it showed resistance to malathion (with mortality rates ranging from 49% to 78%) in all districts except Angul in Odisha and Palwal in Haryana. In addition, resistance to deltamethrin was observed in districts of Maharashtra, Gujarat, Haryana, and Karnataka. CONCLUSIONS: Our study offers vital insights into the prevalence, resting behavior, and sibling species composition of malaria vectors in India. It is evident from our findings that resistance development in An. culicifacies, the primary vector, to synthetic pyrethroids is on the rise in the country. Furthermore, the results of our study suggest a potential change in the resting behavior of An. culicifacies in Madhya Pradesh, although further studies are required to confirm this shift definitively. These findings are essential for the development of effective vector control strategies in India, aligning with the goal of malaria elimination by 2030.

Influence of climatic factors on the life stages of Aedes mosquitoes and vectorial transmission: A review.

BACKGROUND OBJECTIVES: Aedes aegypti and Aedes albopictus are two sympatric mosquito species that compete with each other for resources when their breeding habitats overlap. This study examines what happens when sympatric Aedes aegypti and Aedes albopictus mosquitoes' mate with each other and other species by looking at insemination rates, fecundity, and hatchability rate. METHODS: We performed controlled mating experiments in laboratory setting, assessing both conspecific and interspecific crosses. We measured insemination rates, egg numbers, and hatching success to examine the reproductive interference dynamics between these two distinct mosquito species. RESULTS: In the context of conspecific mating, it was observed that both female Ae. aegypti and Ae. albopictus exhibited high insemination rates, with percentages of 98% and 94%, respectively. However, interspecific mating exhibited interesting asymmetries: Ae. albopictus males achieved a notable insemination success rate of 28% when mating with Ae. aegypti females, while Ae. aegypti males achieved only 8% insemination success with Ae. albopictus females. Additionally, females that mated with interspecific males had reduced production of viable eggs compared to conspecific mating. Most notably, interspecific mating resulted in the production of infertile eggs, while conspecific mating led to successful hatching. INTERPRETATION CONCLUSION: The study reveals that, Ae. aegypti and Ae. albopictus can asymmetrically interfere with each other's reproduction, causing a 'satyr' effect. This understanding of interspecific competition and reproductive interference in these mosquito species could impact their coexistence in shared breeding habitats.

Impact of urbanization on the abundance and distribution of Anophelines population in Ghaziabad district, Uttar Pradesh, India.

BACKGROUND OBJECTIVES: In urban areas, upsurge in population has resulted in more breeding sites for malaria vectors, and hence this scenario potentially undermine malaria elimination and control programs. The change in land use due to urbanization may result in the presence and distribution of malaria vectors. Understanding potential malaria vectors is essential for current and future malaria transmission control strategies. This study investigated the effects of rapid urbanization on malaria vectors An. culicifacies s.l. and An. stephensi L. in Ghaziabad district. METHODS: Ghaziabad district which presents several levels of urbanization was selected for this study. Entomological investigations were conducted seasonally from 2014-2016 in the rural, urban, and peri-urban regions. Vector incrimination study was done using ELISA (confirmation by PCR) on suspected Anopheles vectors viz. An. culicifacies, An. stephensi, An. annularis and An. subpictus. RESULTS: An. culicifacies showed alteration in distribution influenced by rural and agricultural land whereas An. stephensi was found to be influenced by artificial habitats and population growth. INTERPRETATION CONCLUSION: The study also confirms the association between the abundance of malaria vectors and land use change.

Mild Cognitive Impairment among Elderly Persons Residing in an Urban Resettlement Colony in Delhi.

Background: Mild cognitive impairment (MCI) is a transitional state between normal cognition and clinical dementia. MCI is associated with an increased risk of dementia and mortality. Progression of MCI to dementia can be prevented by cognitive and lifestyle interventions. There is limited evidence on the burden and risk factors associated with MCI in India. To estimate the prevalence of MCI among elderly persons, and to study the factors associated with MCI. Materials and Methods: This community-based cross-sectional study was carried out among 365 persons aged 60 years or older, residing in an urban resettlement colony of Delhi. Participants with dementia (score <23 on the Hindi version of the Mini-Mental State Examination) were excluded. Objective cognitive impairment and functional disability were assessed by the Montreal Cognitive Impairment-Basic (MoCA-B) tool and Barthel's Activities of Daily Living, respectively. The prevalence of MCI was estimated by Petersen's criteria, i.e., subjective memory impairment, objective cognitive impairment (MoCA score 19-25), functional independence, and absence of dementia. Univariate analysis was performed, followed by stepwise multivariate logistic regression. The association of socio-demographic and other health conditions with MCI was assessed. Results: The prevalence of MCI was 9.3% [95% confidence interval (CI) 6.7-12.7], 13.3% (95% CI 8.8-19.7) among men, and 6.5% (95% CI 3.9-10.6) among women. The risk of MCI was higher among current smokers. Conclusions: MCI was common among the elderly. Early detection of MCI may be included in health programs for elderly persons.

Maternal Healthcare Services in a Rural Area of Haryana during the COVID-19 Pandemic: A Community-Based Study.

Background: It is well documented that the utilization of maternal healthcare services during pregnancy and childbirth plays a significant role in reducing maternal morbidity and mortality. Disruptions in maternal healthcare services during the coronavirus disease 2019 (COVID-19) pandemic have been reported. However, there is a paucity of literature from rural areas, as most of the previous studies are either record-based or conducted in tertiary care centers. This study aimed to determine the proportion of women who received the recommended maternal healthcare services during the COVID-19 pandemic and to study various factors associated with the utilization of services. Material and Methods: In this community-based study, we assessed the utilization of maternal healthcare services among 520 women residing in the Ballabgarh Block of District Faridabad, Haryana, whose antenatal, intrapartum, and postnatal period coincided with the first wave of COVID-19 pandemic. Domiciliary visits were made, and women were interviewed retrospectively regarding maternal healthcare services utilized by them. The antenatal care (ANC) cards were reviewed, and details were corroborated. Results: Full ANC was received by 15.3% of women, and 45% of women had less than four antenatal visits. 30.9% of participants had cesarean delivery. The proportion of cesarean delivery in private facilities was significantly higher than in government facilities [Odds Ratio (OR) (95% Confidence intervals (CI)) =10.04 (5.87-17.19); P < 0.001]. In multivariate logistic regression, gravidity was negatively associated with full ANC [OR (95% CI) =0.43 (0.25-0.74); P = 0.002]. Conclusion: Fewer women received the recommended maternal healthcare services during the COVID-19 pandemic. Detailed assessment of health systems and factors affecting routine healthcare services, during the pandemic, can help improve the readiness and response in the future.

Susceptibility status of Aedes aegypti (Diptera: Culicidae) against insecticides of public health use in Delhi and NCR region, India.

BACKGROUND & OBJECTIVES: Aedes (Stegomyia) aegypti is a primary vector responsible for the transmission of various arboviral diseases in India. Without an effective drug or vaccine against these diseases, chemical insecticide-based vector control supplemented with source reduction remains the best option for their effective management. The development of insecticide resistance due to the continuous use of insecticides might affect the control operations. METHODS: Adults and larvae of Aedes aegypti were collected from different localities in Delhi. Larvae were exposed to discriminating (0.02mg/l) and application (1mg/l) doses of temephos. WHO tube assay was conducted for F1 adults using impregnated insecticide papers of dichlorodiphenyltrichloroethane (DDT), malathion, deltamethrin, permethrin, cyfluthrin, and lambda-cyhalothrin. RESULTS: Larvae of Ae. aegypti were found resistant (76.0%) to the discriminating dose of temephos, whereas suscep-tible (100.0%) to the application dose of the temephos. Adult Aedes (Fl) mosquitoes were resistant to DDT (23.7%), malathion (90.5%), deltamethrin (76.0%), permethrin (96.2 %) cyfluthrin (85.5%), and lambda-cyhalothrin (94.0%). INTERPRETATION & CONCLUSION: Indoor residual spray is not used in Delhi for vector control. Resistance in Aedes might be due to pesticide usage for agricultural activities in peripheral regions of Delhi. There is a need to investigate more on the insecticide resistance mechanisms for indirect resistance development. Understanding the insecticide susceptibility status of urban vectors is critical for planning effective control strategies.

Aedes aegypti container preference for oviposition and its possible implications for dengue vector surveillance in Delhi, India.

OBJECTIVES: Dengue is a mosquito-borne viral disease globally transmitted by Aedes aegypti. The most effective method to prevent the transmission of the disease is proficient vector control. Understanding the breeding behaviour of the responsible vectors is very pertinent in this regard; therefore, the present study was conducted to understand Ae. aegypti behaviour regarding the selection of containers for oviposition in the megacity of Delhi. METHODS: A household survey in different localities within Delhi was carried out during 2018-2019. All available containers were inspected for the presence of immature Ae. aegypti. In entomological surveillance, the ovipositional preference of Aedes was computed using the breeding preference ratio, container index in the field, and laboratory settings, and associations of dengue cases with monthly variation in environmental factors and container type were also calculated. RESULTS: The household larval survey in 40 localities showed that 40% of 27,776 water-holding containers in 3,400 houses were plastic, followed by overhead tanks (26.2%), and coolers (12.1%). The most preferred breeding habitat was clay pots (9.3%), followed by metallic containers (8.5%) and solid waste (7.1%). A laboratory-based study showed that Aedes preferred clay containers (81.8%) over 4 other types of containers (plastic, paper, metal, and glass). CONCLUSIONS: The present study provides a rationale for using clay containers as a possible surveillance tool (ovitraps) or as a vector control tool. This information might aid researchers in developing novel traps and targeting preferred containers for larval control activities during transmission and non-transmission seasons.

Acute myeloid leukemia with RAM immunophenotype: A new underdiagnosed entity.

INTRODUCTION: Acute myeloid leukemia (AML) with RAM immunophenotype is a distinct subtype of AML, as described by the Children's Oncology Group (COG), with characteristic morphological and immunophenotypic properties. It is characterized by strong CD56 expression with dim to negative CD45, HLA-DR, and CD38 expression. It is an aggressive leukemia with a poor response to induction chemotherapy and/or frequent relapses. METHODS: Seven cases with the characteristic RAM immunophenotype were identified in this retrospective analysis of newly diagnosed pediatric AML cases from January 2019 to December 2021. Herein, we have critically analyzed their clinical, morphological, cytochemical, immunophenotyping, cytogenetic, and molecular profiles. The patients were traced and followed for their current disease and treatment status. RESULTS: Of 302 cases of pediatric AML (age <18 years), seven cases (2.3%) with the distinct RAM phenotype were observed, with age ranging from 9 months to 5 years. Two patients were misdiagnosed earlier as small round cell tumor because of the strong CD56 positivity and the absence of leukocyte common antigen (LCA), but they were later correctly identified as granulocytic sarcoma. The bone marrow aspirate showed blasts with unusual cohesiveness and clumping with nuclear moulding, mimicking non-hematologic malignancies. Flow cytometry revealed blasts with low side scatter, dim to negative CD45 and CD38, negative cMPO, CD36, and CD11b; moderate to bright CD33, CD117, and bright CD56. The Mean fluorescence intensity (MFI) of CD13 expression was significantly lower as compared to the internal controls. Cytogenetic and molecular studies did not show any recurrent abnormalities. Reverse transcription polymerase chain reaction for CBFA2T3-GLIS2 fusion was performed in 5/7 cases, with one positive result. On clinical follow-up, two patients were refractory to chemotherapy. Six of the seven cases had succumbed to death (duration of survival: 3-343 days after initial diagnosis). CONCLUSION: AML with RAM immunophenotype, a distinct form of pediatric AML with a poor prognosis, may pose a diagnostic challenge if presented as a soft tissue mass. A comprehensive immunophenotypic evaluation, including stem cell and myeloid markers, is critical for an accurate diagnosis of myeloid sarcoma with the RAM-immunophenotype. Our data demonstrated weak CD13 expression as an additional immunophenotypic finding.

CD34 negative HLA-DR negative acute myeloid leukaemia: A higher association with NPM1 and FLT3-ITD mutations.

INTRODUCTION: CD34 and HLA-DR negativity is often used as a characteristic immunophenotypic feature of acute promyelocytic leukaemia (APL) that differentiates APL from other subtypes of acute myeloid leukaemia (AML). However, other subtypes of AML, without expression of CD34 and HLA-DR antigens, have also been reported. METHODS: We analysed the HLA-DR negative de novo non-APL AML cases by dividing HLA-DR negative non-APL group into 2 sub-groups based on CD34 expression and compared the characteristics of CD34 negative HLA-DR negative with CD34 positive HLA-DR negative non-APL AML cases with respect to morphologic, immunophenotypic, molecular and clinical parameters. RESULTS: There were 70 cases (8.54%) which were CD34 negative HLA-DR negative and 52 cases (6.34%) were CD34 positive HLA-DR negative. The median age at diagnosis was higher in CD34 negative HLA-DR negative AML than in CD34 positive HLA-DR negative AML group (38 years vs. 12 years, p < 0.001). DIC rate was higher in CD34 negative HLA-DR negative group than the other group (p < 0.001). Median total leucocyte count was higher with higher blast count in peripheral blood and bone marrow in CD34 negative HLA-DR negative AML cases than the other group (p < 0.05). CD34 negative HLA-DR negative AML was more associated with normal karyotype (96.2% vs. 38.5%; p < 0.001), NPM1 mutation (67.8% vs. 8.3%; p < 0.001) and FLT-ITD mutation (37.3% vs. 13.9%; p < 0.05). In CD34 negative HLA-DR negative group, 16 cases had co-occurrence of NPM1 and FLT3-ITD mutations, whereas no case of CD34 positive HLA-DR negative group had such dual mutation positivity. There was poor median overall survival [3.8 months (95%CI: 2.3-7.8 months) vs. 20.4 months (95% CI: 12.8-25.7 months); p = 0.0148] in CD34 positive HLA-DR negative AML than CD34 negative HLA-DR negative AML cases. CONCLUSION: We found that the CD34 negative HLADR negative non APL AML is highly associated with NPM1 and FLT3-ITD mutation, older age at diagnosis, DIC, higher total leucocyte count, higher blast counts and normal karyotype in comparison to CD34 positive HLA-DR negative AML group. Co-occurrence of NPM1 and FLT3-ITD mutation was also exclusively seen in CD34 negative HLA-DR negative group. There was poor overall survival in CD34 positive HLA-DR negative AML than CD34 negative HLA-DR negative AML cases.

Effect of COVID-19 pandemic on utilization of maternal healthcare services in a rural area of Haryana - A record-based comparative study.

Background: The COVID-19 pandemic posed a challenge for the public health system, as all the health facilities and manpower were diverted for the delivery of COVID-19-related services. This affected the provision of routine health services, including maternal healthcare services. There is a paucity of data from rural and primary healthcare settings, as the earlier studies were either modelling-based or from tertiary care centres. Materials and Methods: This record-based study was conducted in 12 subcentres in the district Faridabad of Haryana. Data of pregnant women registered during 1 April to 30 September in the years 2017-2020 were retrieved. The utilization of maternal healthcare services among women registered during 1 April 2020 to 30 September 2020 was compared with those registered in the same period during the preceding 3 years (2017-2019). Results: There was a significant decline in utilization of maternal healthcare services. Services like minimum four antenatal visits declined from 67.8% to 48.3% (P < 0.0001), at least 100 iron-folic acid tablets (45.4-20.9%; P < 0.001), and examination at each visit (90.8-72.3%; P < 0.001). The proportion of pregnant women who received full antenatal care decreased from 26.0% to 10.7% (P < 0.001). There was a significant increase in delivery in private health facilities (40.9-49.9%) and delivery by caesarean section (21.6-27.3%; P = 0.002). Conclusion: COVID-19 pandemic had an adverse effect on utilization of maternal healthcare services. Effective planning and coordination between different levels of government health facilities and primary care providers, including family physicians, can ensure uninterrupted provision of essential services during similar emergencies in future.

Clinical and Prognostic Impact of Copy Number Alterations and Associated Risk Profiles in a Cohort of Pediatric B-cell Precursor Acute Lymphoblastic Leukemia Cases Treated Under ICiCLe Protocol.

Copy number alteration (CNA) status and CNA risk profiles of IKZF1 plus , UK-ALL CNA risk groups and MRplus scores, were evaluated for clinical and prognostic impact in a cohort of 493 B-cell acute lymphoblastic leukemia cases diagnosed and treated under the Indian Collaborative Childhood Leukemia group (ICiCLe) protocol trial. Overall CNA frequency was 59% with 60% of cases showing 2-loci deletion. CDKN2A/B deletion was most common CNA (36.3%), while IKZF1 deletion and IKZF1 plus profile were noted in 19.5% and 13.4% of cases, respectively. IKZF1 deletions and other CNA risk profiles were significantly associated with poor (PR)/high risk (HR) clinical and genetic profile parameters (P < 0.001). In addition, the 3-year OS, event-free survival (EFS) was significantly poor with high relapse rate (RR) of 38.6%, 46.5%, and 35.2% for IKZF1 deletions, IKZF1 plus profiles, and UK-ALL CNA-intermediate risk (IR)+PR risk groups, respectively (P < 0.001). Integrated evaluation of UK-ALL CNA risk profile with ICiCLe trial risk stratification groups revealed a worse overall survival, EFS, and RR of 63.3%, 43.2%, and 35.2% for CNA-IR+PR profile compared to CNA-good risk profile (81.3%, 65.0%, and 21.0%; P < 0.001). Hence, routine CNA testing in our setting is must to identify standard risk and IR cases likely to benefit from HR treatment.

Challenges in Understanding the Bionomics of Indian Malaria Vectors.

Many factors influence the success or failure of malaria vector control program such as political will, leadership, sustained funding, robustness of healthcare system and others. In addition, updated knowledge and information about the triad of host, parasite, and vector is of paramount importance. Vector bionomics studies that determine mosquito behavior in terms of feeding, resting, biting, mating, breeding, longevity, vectorial capacity, and response to different insecticides are a step towards enhancing our understanding. In the present work, we have compiled studies conducted in India over the past two decades (2000-2020) to identify gaps in our knowledge of malaria vector bionomics and the research that needs to be done in the future. We retrieved district-level data of India's six primary malaria vector species. According to our findings, vector bionomics studies have been undertaken in ∼50% and ∼15% of the country's high (annual parasite index > 1) and low (annual parasite index < 1) malaria-endemic districts respectively. Most of the research studies focused on mosquito density, insecticide susceptibility status, and parasite detection, whereas other vital bionomics parameters were neglected. Surveys conducted were incomplete, and vector bionomics data were not captured sufficiently. The absence of vector bionomics data can be a blind spot and the lack or inadequate understanding of vector bionomics can lead to use of inappropriate vector control tools. Thus, there is an urgent need to initiate comprehensive bionomics studies on India's primary and secondary malaria vectors.

Excess Screen Time and its Associated Factors among Young Men in a Rural Community of North India.

Screen-based media usage among young people is blooming rapidly due to technological and digital revolution. We conducted community-based cross-sectional study to determine the prevalence of excess screen time and its association with sociodemographic and behavioral patterns in a rural block of Haryana, India. A semi-structured interview schedule was administered by trained physicians to ascertain screen time in a typical day and various socioeconomic and behavioral factors among a random sample of 860 young men aged 18-24 years. The prevalence of excess screen time was 61.8% (95% confidence interval [CI] 58.4-65.1). It was significantly associated with education (adjusted odds ratio [AOR] 1.7, 95% CI 1.1-2.6) and occupation (AOR 2.2, 95% CI 1.2-3.9) of the father and their sleep duration of ≤8 h (AOR 1.6, 95% CI 1.2-2.3). Limiting the screen time as per international standards and behavioral interventions are needed for this young population.

Surveillance of Zika and Dengue viruses in field-collected Aedes aegypti mosquitoes from different states of India.

The emergence of Zika created a panic situation worldwide and burdened the public health system of the affected countries. In India, Zika outbreak occurred in 2017 and in July 2021 one laboratory-confirmed case was also reported in Kerala state. The study aimed to assess any positivity in field-collected mosquitoes for ZIKV and DENV during 2016-2021. Mosquito samples were received from 4 Zika affected citites, whereas samples were collected from Delhi. Out of 2346 pools, 4 pools for ZIKV, and 23 pools for DENV were found positive. ZIKV positive pools were from Shastri Nagar, Jaipur (2 pools), Rajpur Hotel, Jaipur (1 pool) and Kanpur (1 pool). Ten localities of Delhi were found positive for DENV. It was observed that the maximum positivity rate for both viruses were found in September-October. The active role of the vector in local transmission of ZIKV warrants regular surveillance and monitoring of Aedes vectors in India.

Prevalence of asthma among children in India: A systematic review and meta-analysis.

There is a lack of national-level estimates on the magnitude of asthma among children in India. Hence, we undertook a systematic review and meta-analysis to estimate the prevalence of asthma among children in India. We searched PubMed, Embase, Cochrane Library, and Google Scholar, and included cross-sectional studies reporting data on the prevalence of asthma among children in India. A random-effects model was used to estimate the pooled prevalence of asthma. In the 33 selected studies (pooled sample of 167,626 children), the estimated prevalence of asthma was 7.9% (95% confidence interval: 6.3-9.6%), I2 = 99.1% (P < 0.001). The prevalence was higher among boys and in urban areas. Appropriate training and resources should be made available at the primary healthcare level for early detection and management of asthma in children. A nationwide population-based survey is indicated to provide reliable estimates of the burden of asthma.

Prevalence and Factors Associated with Hypertension among Community-Dwelling Adolescents in a Rural Area of Haryana, India, Using AAP 2017 and NHBPEP Criteria.

OBJECTIVE: To estimate the prevalence and determinants of hypertension among adolescents in a rural area in North India. METHODS: This was a cross-sectional study conducted among community-dwelling adolescents (10-19 y) and defined blood pressure as per the National High Blood Pressure Education Program (NHBPEP) and American Academy of Pediatrics (AAP) 2017 criteria. A pretested, semistructured questionnaire was used to elicit sociodemographic details and risk factors of hypertension. Association of factors with hypertension, z scores of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were assessed by logistic and linear regression. In multivariable regression model, for both logistic and linear regression, variables with p value < 0.2 were included, excluding collinear variables. RESULTS: Eight hundred sixty-four adolescents participated with mean (SD) age, BMI of 14.0 ± 2.6 y, 18.3 ± 3.5 kg/m2. Hypertension prevalence was 22.5% (95% CI: 19.7, 25.5) as per AAP and 15.2% (95% CI: 12.9, 17.8) as per NHBPEP criteria. Being hypertensive as per the AAP was associated with family history of noncommunicable disease (NCD) (adjusted odds ratio, AOR 1.80, 95% CI: 1.11, 2.86) and BMI (AOR = 1.09, 95% CI: 1.04, 1.14), and as per the NHBPEP, was only associated with BMI (AOR = 1.11, 95% CI: 1.05, 1.17). SBP z score was significantly associated with male sex (adjusted beta coefficient AC = 0.79, 95% CI: 0.69, 0.90), and weight z scores (AC = 2.00, 95% CI: 1.22, 3.28); DBP z score was significantly associated with z scores of height (AC = 0.70, 95% CI: 0.51, 0.96) and waist (AC = 1.15, 95% CI: 1.02, 1.30). CONCLUSION: The prevalence of hypertension among adolescents was high and was associated with BMI and family history of NCD.
