We present the study of the SiGe quantum ring (QR) modeled by an anharmonic axially symmetric potential with a centrifugal core in the effective mass approximation. We show how the femtosecond laser pulses (FLPs) can be used efficiently for controlling the induced current and magnetic field. We have compared the strength of induced currents and magnetic fields with and without pulsed laser which shows a substantial change. The spin-orbit interaction (SOI) and Zeeman energy show a massive impact on the generation and enhancement of these induced current and magnetic fields. These induced currents and magnetic fields have many applications in interdisciplinary areas. We have shown that the SOI presence with the FLP fields while competing with the confinement strength lowers the strength of the induced current and field.

Young people's health has emerged as a neglected yet pressing issue in global development. Changing patterns of young people's health have the potential to undermine future population health as well as global economic development unless timely and effective strategies are put into place. We report the past, present, and anticipated burden of disease in young people aged 10–24 years from 1990 to 2013 using data on mortality, disability, injuries, and health risk factors. The Global Burden of Disease Study 2013 (GBD 2013) includes annual assessments for 188 countries from 1990 to 2013, covering 306 diseases and injuries, 1233 sequelae, and 79 risk factors. We used the comparative risk assessment approach to assess how much of the burden of disease reported in a given year can be attributed to past exposure to a risk. We estimated attributable burden by comparing observed health outcomes with those that would have been observed if an alternative or counterfactual level of exposure had occurred in the past. We applied the same method to previous years to allow comparisons from 1990 to 2013. We cross-tabulated the quantiles of disability-adjusted life-years (DALYs) by quintiles of DALYs annual increase from 1990 to 2013 to show rates of DALYs increase by burden. We used the GBD 2013 hierarchy of causes that organises 306 diseases and injuries into four levels of classification. Level one distinguishes three broad categories: first, communicable, maternal, neonatal, and nutritional disorders; second, non-communicable diseases; and third, injuries. Level two has 21 mutually exclusive and collectively exhaustive categories, level three has 163 categories, and level four has 254 categories. The leading causes of death in 2013 for young people aged 10–14 years were HIV/AIDS, road injuries, and drowning (25·2%), whereas transport injuries were the leading cause of death for ages 15–19 years (14·2%) and 20–24 years (15·6%). Maternal disorders were the highest cause of death for young women aged 20–24 years (17·1%) and the fourth highest for girls aged 15–19 years (11·5%) in 2013. Unsafe sex as a risk factor for DALYs increased from the 13th rank to the second for both sexes aged 15–19 years from 1990 to 2013. Alcohol misuse was the highest risk factor for DALYs (7·0% overall, 10·5% for males, and 2·7% for females) for young people aged 20–24 years, whereas drug use accounted for 2·7% (3·3% for males and 2·0% for females). The contribution of risk factors varied between and within countries. For example, for ages 20–24 years, drug use was highest in Qatar and accounted for 4·9% of DALYs, followed by 4·8% in the United Arab Emirates, whereas alcohol use was highest in Russia and accounted for 21·4%, followed by 21·0% in Belarus. Alcohol accounted for 9·0% (ranging from 4·2% in Hong Kong to 11·3% in Shandong) in China and 11·6% (ranging from 10·1% in Aguascalientes to 14·9% in Chihuahua) of DALYs in Mexico for young people aged 20–24 years. Alcohol and drug use in those aged 10–24 years had an annual rate of change of >1·0% from 1990 to 2013 and accounted for more than 3·1% of DALYs. Our findings call for increased efforts to improve health and reduce the burden of disease and risks for diseases in later life in young people. Moreover, because of the large variations between countries in risks and burden, a global approach to improve health during this important period of life will fail unless the particularities of each country are taken into account. Finally, our results call for a strategy to overcome the financial and technical barriers to adequately capture young people's health risk factors and their determinants in health information systems.

Better childhood health and nutrition, extensions to education, delays in family formation, and new technologies offer the possibility of this being the healthiest generation of adolescents ever. But these are also the ages when new and different health problems related to the onset of sexual activity, emotional control, and behaviour typically emerge. Global trends include those promoting unhealthy lifestyles and commodities, the crisis of youth unemployment, less family stability, environmental degradation, armed conflict, and mass migration, all of which pose major threats to adolescent health and wellbeing.

To understand the impact of COVID-19 on implementation of the peer education programme of the National Adolescent Health Programme-Rashtriya Kishor Swasthya Karyakram (RKSK); repurposing of the RKSK health workers and Peer Educators (PEs) in COVID-19 response activities and effect on adolescents´ health and development issues. Virtual in-depth interviews were conducted with stakeholders (n = 31) (aged 15 to 54 years) engaged in the implementation of the RKSK and peer education programme at state, district, block, and village levels in Madhya Pradesh and Maharashtra (India). These interviews were thematically coded and analysed to address the research objectives. Despite most peer education programme activities being stopped, delayed, or disrupted during the pandemic and subsequent lockdown, some communication networks previously established, helped facilitate public health communication regarding COVID-19 and RKSK, between health workers, PEs, and adolescents. There was repurposing of RKSK health workers and PEs' role towards COVID-19 response-related activities. PEs, with support from health workers, were involved in disseminating COVID-19 information, maintaining migrant and quarantine records, conducting household surveys for recording COVID-19 active cases and providing essential items (grocery, sanitary napkins, etc.) to communities and adolescents. PEs with support from community health workers are able to play a crucial role in meeting the needs of the communities during a pandemic. There is a need to further engage, involve and build the skills of PEs to support the health system. PEs can be encouraged by granting more visibility and incorporating their role more formally by paying them within the public health system in India.

Background Food policies and environment (availability, accessibility, affordability, marketing) in and around educational institutes can influence food choices and behaviours of children and adolescents. Methods Cross-sectional, mixed-methods study was implemented in schools ( n  = 9; Private = 6, Public = 3) and colleges ( n  = 4) from Delhi and National Capital Region (India). The data was collected from students of schools ( n  = 253) and colleges ( n  = 57), parents of school students ( n  = 190), teachers ( n  = 12, schools = 9, colleges = 3) and canteen operators of Private schools and colleges ( n  = 10; schools = 6, and colleges = 4). The primary and secondary data was collected to: 1) identify the strengths and weaknesses of the existing guidelines and directives (desk review); 2) examine food environment, existing policies and its implementation (structured observations, in-depth interviews, surveys, focus group discussions), and; 3) assess food choices, behaviours of students (focus group discussions). The thematic analysis was used for qualitative data and descriptive analysis for quantitative data. Results The available food and beverage options, in and around the participating educational institutes were either high in fat, salt and sugar (HFSS), despite government and educational institute guidelines on restricting the availability and accessibility of HFSS foods. The healthy food and beverage options were expensive compared to HFSS foods both inside and outside educational institutes. In total, 37 vendors (Private = 27; Public:10) were observed outside schools at dispersal and twelve at lunchtime. Around colleges, vendors ( n  = 14) were seen throughout the day. Students from all Private schools ( n  = 6) and colleges ( n  = 2) were exposed to food and beverage advertisements either HFSS (Private schools = 1–3 and colleges = 0–2 advertisements), whereas no advertisements were observed around Public schools. Conclusion It is imperative to implement food policies to improve the food environment in and around educational institutes to ensure the availability of healthy foods to establish and sustain healthy eating behaviours among students. Thus, the study findings emphasise stringent implementation, regular monitoring and surveillance of recently introduced Food Safety and Standards (Safe food and balanced diets for children in school) Regulation 2020, ensuring its compliance through effective enforcement strategies.

Background Over the past few years, there has been a global shift in the food consumption pattern from traditional home cooked meals to ultra-processed packaged foods (UPFs). Adolescents are the most avid consumers of UPFs, with these foods comprising nearly 16.2% of total daily energy intake among Indian adolescents. Adolescence is a critical period for establishing autonomous dietary choices and habits, which often persist into adulthood and are strongly linked to long-term health outcomes, including obesity, diabetes, and cardiovascular disease. Therefore, empowering adolescents to make informed food choices is critical for both immediate and future public health. Globally, the implementation of user-friendly food labelling has been proven to improve consumer understanding and is recognized as an effective public health strategy for promoting healthier food choices. This review aimed to assess the extent (volume of literature available) and range (the variety of research done) of evidence available on promoting food label literacy and/or healthy food choices among adolescents through education-based interventions. Methods An extensive literature search was conducted to select relevant research articles using a predetermined inclusion criterion. The literature search was done across different databases like PubMed, Scopus, Embase and Google scholar. The databases were searched for records published between the time frame 2000 to 2024. A total of 4,380 articles were manually screened, yielding 221 titles for further review. Of these, 169 abstracts and subsequently 44 full-text articles were assessed for eligibility using software. Ultimately, 11 full-text articles met the inclusion criteria and were incorporated into the scoping review. Results The findings of the selected 11 studies were synthesized to highlight methods that promote food label reading and healthy food choices among adolescents. This review identified effective educational interventions for improving food label literacy and healthy food choices among adolescents commonly utilized behaviour change models, tailored content, and participatory approaches. Most interventions were school based, delivered through lectures or interactive activities, with some incorporating digital media and real food label analysis. Statistically significant improvements in food label knowledge were reported in the majority of studies, with positive impacts also observed on label use practices and food choices. These findings highlight the importance of context-specific, engaging, and theory-driven strategies in adolescent nutrition education. Conclusions The study concluded that such educational interventions have been primarily conducted in schools (mode), using educational materials and food models (as media) through lecture-based delivery (method). Invariably this approach enhances food label knowledge of adolescents, however, challenges remain in translating this knowledge into long term practices and healthy food choices.

ObjectiveTo assess the changes in prevalence of past-year self-reported sexually transmitted infections (STIs) and its symptoms among married couples between 2006 and 2016 in India, overall and by socioeconomic status.DesignThis cross-sectional study uses the two most recent waves (2005–2006 vs 2015–2016) of nationally representative health surveys in India. We examined the changes of self-reported STI and symptoms among married couples aged 15–54 by overall and by socioeconomic status. Adjusted logistic regression was used to assess the changes, accounting for covariates and the complex survey design.SettingCross-sectional, nationally representative population-based survey in 2005–2006 and 2015–2016 from National Family Health Survey data from Demographic and Health Survey.Participants39 257 married couples aged 15–49 years for the 2005–2006 survey wave and 63 696 married couples aged 15–49 years for the 2015–2016 wave.Outcome measureSelf-reported STI was used as a primary outcome measure.ResultsIn 2016, 2.5% of married women reported having had an STI in the past year, a significant increase from 1.6% in 2006 (p<0.001). The past-year self-reported STI prevalence among married men significantly increased from 0.5% in 2006 to 1.1% in 2016 (p<0.001). Adjusted results showed that the uptrend of couples’ self-reported STI was more significant among those whose husbands are currently employed and those families in middle or higher wealth quintiles. Alarmingly, among couples who reported STI or symptoms, they were less likely to seek advice or treatment in 2016 as compared with 2006 (adjusted OR=0.50, p<0.001, 95% CI=0.40 to 0.61).ConclusionThe study identifies a substantial increase in self-reported STI prevalence with a notable treatment seeking gap among married couples in India over the past decade.

In high-income countries, secondhand smoke (SHS) exposure is higher among disadvantaged groups. We examine socioeconomic inequalities in SHS exposure at home and at workplace in 15 low- and middle-income countries (LMICs). Secondary analyses of cross-sectional data from 15 LMICs participating in Global Adult Tobacco Survey (participants ≥ 15 years; 2008-2011) were used. Country-specific analyses using regression-based methods were used to estimate the magnitude of socioeconomic inequalities in SHS exposure: (1) Relative Index of Inequality and (2) Slope Index of Inequality. SHS exposure at home ranged from 17.4% in Mexico to 73.1% in Vietnam; exposure at workplace ranged from 16.9% in Uruguay to 65.8% in Bangladesh. In India, Bangladesh, Thailand, Malaysia, Philippines, Vietnam, Uruguay, Poland, Turkey, Ukraine, and Egypt, SHS exposure at home reduced with increasing wealth (Relative Index of Inequality range: 1.13 [95% confidence interval [CI] 1.04-1.22] in Turkey to 3.31 [95% CI 2.91-3.77] in Thailand; Slope Index of Inequality range: 0.06 [95% CI 0.02-0.11] in Turkey to 0.43 [95% CI 0.38-0.48] in Philippines). In these 11 countries, and in China, SHS exposure at home reduced with increasing education. In India, Bangladesh, Thailand, and Philippines, SHS exposure at workplace reduced with increasing wealth. In India, Bangladesh, Thailand, Philippines, Vietnam, Poland, Russian Federation, Turkey, Ukraine, and Egypt, SHS exposure at workplace reduced with increasing education. SHS exposure at homes is higher among the socioeconomically disadvantaged in the majority of LMICs studied; at workplaces, exposure is higher among the less educated. Pro-equity tobacco control interventions alongside targeted efforts in these groups are recommended to reduce inequalities in SHS exposure. SHS exposure is higher among the socioeconomically disadvantaged groups in high-income countries. Comprehensive smoke-free policies are pro-equity for certain health outcomes that are strongly influenced by SHS exposure. Using nationally representative Global Adult Tobacco Survey (2008-2011) data from 15 LMICs, we studied socioeconomic inequalities in SHS exposure at homes and at workplaces. The study showed that in most LMICs, SHS exposure at homes is higher among the poor and the less educated. At workplaces, SHS exposure is higher among the less educated groups. Accelerating implementation of pro-equity tobacco control interventions and strengthening of efforts targeted at the socioeconomically disadvantaged groups are needed to reduce inequalities in SHS exposure in LMICs.

Background Globally, non-communicable diseases (NCDs) are identified as one of the leading causes of mortality. NCDs have several modifiable risk factors including unhealthy diet, physical inactivity, tobacco use and alcohol abuse. Schools provide ideal settings for health promotion, but the effectiveness of school policies in the reduction of risk factors for NCD is not clear. This study reviewed the literature on the impact of school policies on major NCD risk factors. Methods A systematic review was conducted to identify, collate and synthesize evidence on the effectiveness of school policies on reduction of NCD risk factors. A search strategy was developed to identify the relevant studies on effectiveness of NCD policies in schools for children between the age of 6 to 18 years in Ovid Medline, EMBASE, and Web of Science. Data extraction was conducted using pre-piloted forms. Studies included in the review were assessed for methodological quality using the Effective Public Health Practice Project (EPHPP) quality assessment tool. A narrative synthesis according to the types of outcomes was conducted to present the evidence on the effectiveness of school policies. Results Overall, 27 out of 2633 identified studies were included in the review. School policies were comparatively more effective in reducing unhealthy diet, tobacco use, physical inactivity and inflammatory biomarkers as opposed to anthropometric measures, overweight/obesity, and alcohol use. In total, for 103 outcomes independently evaluated within these studies, 48 outcomes (46%) had significant desirable changes when exposed to the school policies. Based on the quality assessment, 18 studies were categorized as weak, six as moderate and three as having strong methodological quality. Conclusion Mixed findings were observed concerning effectiveness of school policies in reducing NCD risk factors. The findings demonstrate that schools can be a good setting for initiating positive changes in reducing NCD risk factors, but more research is required with long-term follow up to study the sustainability of such changes.

ObjectivesTo review the overall planning, implementation and monitoring of adolescent and school health programmes currently implemented in India and determine if they are in alignment with the indicators for achieving universal health coverage for adolescents in India.MethodsA rapid review, with key informant interviews and desk review, was conducted using World Health Organization’s tool for Rapid Assessment of Implementation of Adolescent Health and School Health Programmes. Operational guidelines, reports and relevant publications (surveys, policy briefs and meeting proceedings) related to India’s adolescent and school health programmes were reviewed. Key informant interviews were conducted in New Delhi (India) with senior officials from the health and education departments of the Government of India, representatives from the private health sector and civil society organisations. Data were analysed using World Health Organization’s framework for universal health coverage for adolescents and summarised according to the key indicators.ResultsKey informant interviews were conducted with 18 participants: four each from health and education department of the government, one clinician from private health sector and nine representatives from civil society organisations. Manuals and operational guidelines of India’s existing adolescent and school health programmes were reviewed. India’s national adolescent and school health programmes align with many priority actions of the World Health Organization’s framework for delivering universal health coverage for adolescents. These programmes require strengthening in their governance and implementation. While adolescent health and school health programmes have robust monitoring frameworks, however, there is a need to strengthen research and policy capacity.ConclusionsVarious national health programmes have targeted adolescents as a priority population. A better translation of these programmes into implementation is needed so that the investments provided by the government offer sufficient opportunities for building collective national action for achieving universal health coverage with adolescents as an important section of the population.
