Centres of Excellence for Adolescent Health and Development: A Case Study from Uttar Pradesh, India
Adolescents and young adult comprise a significant proportion of India’s population. Although, this group of the population faces serious challenges to their health and well-being. To promote their health and well-being, Centre of Excellence (CoE) at King George’s Medical University, Lucknow, India, serves as an advanced care facility for 10–24-year-old adolescents and young adult women. This paper reports the socio-demographic characteristics of, and health services availed to adolescents and young adults who are visiting the CoE in Lucknow, India. A total of 6038 beneficiaries received clinical services during June 2018–March 2022. Out of total clinical services, 38.37% counselling and 37.53% referral services were utilised. Menstruation (46.29%), sexual and reproductive (28.19%), nutrition (5.91%), and mental health (1.67%) related problems were highly reported. The age of beneficiaries is classified into three categories, i.e., 10–14, 15–19, and 20–24 years. Prevalence of overweight was highest among adolescents aged 20–24 years compared to other age groups. Other than nutrition, late-adolescent girls (15–19) faced more health problems than their counterparts. The percentage of beneficiaries decreased significantly during and post the COVID-19 period (<0.001). Therefore, age-specific programs are currently needed, and interventions need to be designed accordingly.

Minimum dietary diversity and associated factors among lactating mothers in Haryana, India: a community based cross-sectional study
Food adequacy and dietary quality in the lactation period are fundamental for maternal and child health. Lactating mothers are vulnerable to malnutrition because of increased physiological demand, monotonous diet, lactogenesis process, and increased nutrient requirements. The micronutrient adequacy especially among women is not ensured in Indian diet. The dual course of gender bias and poverty, along with lack of knowledge about diet quality are significant impediments in maintaining minimum dietary diversity among Indian women. The study aimed to assess the prevalence of minimum dietary diversity and associated factors among lactating women. A community-based cross-sectional study was conducted among 1236 lactating women through a multistage sampling procedure in Haryana state, India. Data were collected in Computer-assisted personal interviewing (CAPI) using a pretested structured interview schedule. Minimum Dietary Diversity for Women by Food and Agriculture Organization (FAO) was used to calculate the minimum dietary diversity. The mean dietary diversity score among lactating women from the ten food groups was 6.35 ± 2.57 and the prevalence of minimum dietary diversity was 77.1%. The complete model revealed that both individual and household factors can explain the variation in dietary diversity intake. Furthermore, the result of model 2 explained that women aged 31 to 35 years (AOR 5.92,95% (1.87–18.77), graduation and above qualified women (AOR 1.98, 95% (0.96–4.09) and lactating women with high knowledge on nutrition (AOR 2.00, 95% (1.34–4.57) were the significant factors promoting minimum dietary diversity. Three-fourths of the lactating women reached adequate minimum dietary diversity. Younger age, low educational level, and poor nutritional knowledge were significant constraints to achieving minimum dietary diversity. Further improvement in the minimum dietary diversity among lactating women is very much required. It is also advised that exiting platforms dispersing awareness on nutrition should be supported and strengthened.

Outdoor Physical Activity in an Air Polluted Environment and Its Effect on the Cardiovascular System—A Systematic Review
Air pollution is a global public health threat. Evidence suggests that increased air pollution leads to increased cardiovascular morbidity and mortality. The aim of this review was to systematically review and synthesize scientific evidence to understand the effect of performing outdoor physical activity (PA) in a polluted environment on cardiovascular outcomes. This review was developed and reported in accordance with the PRISMA guidelines. Electronic searches in Embase, Web of Science, and PubMed were undertaken through March 2021 initially, and later updated through to 31st January 2022, for observational studies published in peer-reviewed journals that report cardiovascular mortality or morbidity due to outdoor PA in air polluted environment. These searches yielded 10,840 citations. Two reviewers independently reviewed each citation for its eligibility. Seven studies were found to be eligible. Of these, five were cohort studies and two were cross-sectional studies. Pollutants measured in the selected studies were Particulate Matter (PM)—PM10, PM2.5, nitrogen oxides (NOx), and ozone (O3). The most common study outcome was myocardial infarction, followed by cardiovascular mortality, hypertension and heart rate variability. Six studies emphasized that the PA has beneficial effects on cardiovascular outcomes, though air pollutants attenuate this effect to an extent. Two studies showed that walking, even in the polluted environment, significantly reduced the heart rate and heart rate variability indices. The beneficial effects of outdoor PA outweigh the harmful effects of air pollution on cardiovascular health, though the benefits reduce to an extent when PA is carried out in a polluted environment. Because a limited number of studies (n = 7) were eligible for inclusion, the review further emphasizes the critical need for more primary studies that differentiate between outdoor and indoor PA and its effect on cardiovascular health.

Mental Health Interventions among Adolescents in India: A Scoping Review
Early adolescence is the period of the emergence of most mental disorders contributing significantly to the mental health burden globally, including India. The major challenges in India are early identification of mental health problems, treatment gap, lack of professionals, and interventions that address the same. Our review aimed to assess the effectiveness of mental health interventions among adolescents in India. We systematically searched PubMed, PsycINFO, and Cochrane databases and used cross-referencing to review the interventions published from 2010 to 2020. Eleven interventions were included in this review; nine were school-based, one community, and one digital. Most of the school-based programs used a life skills curriculum. Additionally, coping skills and resilience curricula showed improvement in depressive symptoms, cognitive abilities, academic stress, problem-solving, and overall mental well-being. The multi-component whole-school intervention was quite promising and helped in improving the overall school climate and various other mental health outcomes. Hence, school-based programs should be implemented as an entry point for screening mental health problems. However, there is a need for a more comprehensive mental health program in the country for adolescents. Additionally, there is a need to address the gap by conducting more interventions for early and out-of-school adolescents.

Scoping Review of Intervention Strategies for Improving Coverage and Uptake of Maternal Nutrition Services in Southeast Asia
Maternal undernutrition can lead to protein-energy malnutrition, micronutrient deficiencies, or anemia during pregnancy or after birth. It remains a major problem, despite evidence-based maternal-nutrition interventions happening on ground. We conducted a scoping review to understand different strategies and delivery mechanisms to improve maternal nutrition, as well as how interventions have improved coverage and uptake of services. An electronic search was conducted in PubMed and Google Scholar for published studies reporting on the effectiveness of maternal-nutrition interventions in terms of access or coverage, health outcomes, compliance, and barriers to intervention utilization. The search was limited to studies published within ten years before the initial search date, 8 November 2019; later, it was updated to 17 February 2021. Of 31 studies identified following screening and data extraction, 22 studies were included for narrative synthesis. Twelve studies were reported from India and eleven from Bangladesh, three from Nepal, two from both Pakistan and Thailand (Myanmar), and one from Indonesia. Nutrition education and counselling, home visits, directly observed supplement intake, community mobilization, food, and conditional cash transfer by community health workers were found to be effective. There is a need to incorporate diverse strategies, including various health education approaches, supplementation, as well as strengthening of community participation and the response of the health system in order to achieve impactful maternal nutrition programs.

Health Workers’ Perceptions about Maternal and Adolescent Health among Marginalized Populations in India: A Multi-Centric Qualitative Study
Frontline workers are instrumental in bridging the gap in the utilization of maternal health services. We performed a qualitative cross-sectional study with medical officers, accredited social health activists (ASHA), and auxiliary nurse midwifes (ANM), across 13 districts of India, in order to understand the barriers and enablers, at the system and population levels, for improving access of adolescents and mothers to services. The data were collected by means of in-depth interviews (IDI) with medical officers and focus group discussions (FGD) with ASHA and ANM in 2016. The interview guide was based on the conceptual framework of WHO health interventions to decrease maternal morbidity. Content analysis was performed. In total, 532 frontline workers participated in 52 FGD and 52 medical officers in IDI. Adolescent clinics seemed nonexistent in most places; however, services were provided, such as counselling, iron tablets, or sanitary pads. Frontline workers perceived limited awareness and access to facilities among women for antenatal care. There were challenges in receiving the cash under maternity benefit schemes. Mothers-in-law and husbands were major influencers in women’s access to health services. Adolescent clinics and antenatal or postnatal care visits should be seen as windows of opportunities for approaching adolescents and women with good quality services.

Comparing Reproductive Health Awareness, Nutrition, and Hygiene among Early and Late Adolescents from Marginalized Populations of India: A Community-Based Cross-Sectional Survey
Adolescence (10–19 years) is marked by many physiological changes and is vulnerable to health and nutritional problems. Adolescence, particularly, early adolescence is inadequately addressed in our national surveys. The present study aimed to assess the reproductive health awareness, nutrition, and hygiene of marginalized adolescent girls and boys and compare them among early and late adolescents. Our cross-sectional study was a part of a community-based project across India’s five zones, namely North, East, West, Central, and South. Unadjusted and adjusted logistic regression was performed to compare awareness about HIV/AIDS, or Sexually Transmitted Infections (STI), consumption of Iron Folic Acid (IFA) tablets and three meals in a day, safe menstrual hygiene practices, history of anemia, and open defecation practice among early and late adolescents. Data were reported as unadjusted and adjusted odds ratio (aOR) with a 95% confidence interval (95% CI). Among early adolescents, around 58% of girls and boys did not consume IFA tablets, and 28% of girls and 24% of boys defecated in the open. Compared to late adolescents, early adolescent girls had lower odds of awareness about HIV/AIDS (aOR (95% CI): 0.50 (0.47–0.54)) and open defecation (aOR (95% CI): 0.90 (0.83–0.98)) and higher odds of hand hygiene after defecation (aOR (95% CI): 1.52 (1.37–1.68)) and safe menstrual practices (aOR (95% CI): 1.42 (1.23–1.64)). There is a dire need to start public health interventions from early adolescence for long-term benefits throughout adolescence.
