Authors:

Abstract

There is lack of standardized and reliable questionnaires to capture various behavioural aspects of subjective health of the population in India and this study was aimed to identify and validate methods and scales measuring determinants of socio-economic inequalities in health in context to Indian adolescents residing in diverse urban areas. In this study scales and questions from internationally validated questionnaires were adopted, and then reliability and validity tests were conducted through a cross sectional study on 1386 Indian adolescents residing in diverse areas of residence (slums, middle class and resettlement colonies) and standardized them to be used on Indian adolescent.

Objective
To identify and validate methods and scales measuring determinants
of social inequalities in health in context to Indian adolescents
Introduction
Health inequalities are major global public health problem and
varies within and between countries [1]. LMICs particularly India,
are undergoing a phase of rapid economic development leading to an
increase in informal settlements or urban slums [2]. These settlements
exhibits extreme poverty and suffers from adverse health outcomes.
The worst affected are the adolescents because it is a crucial and
most vulnerable age when health behaviours and lifestyle choices
are established which affects their current and future health [3].
The current health system in many of the developing countries are
outdated and have either rudimentary health statistics or none. There
is lack of standardized and reliable questionnaires to capture various
behavioural aspects of subjective health of the population in India.
Thus, we aim to identify various measures of determinants of social
inequalities relevant to the Indian adolescent population context.
Methods
We adopted scales and questions from internationally validated
questionnaires, and conducted reliability and validity tests through
a cross sectional study on 1386 adolescents residing in diverse
areas of residence (slums, middle class and resettlement colonies)
and standardized them to be used on Indian adolescent population.
Questionnaire included important determinants of health: degree
of neighbourhood social capital, level of social support, health
related behaviours, self-rated health and key socio-demographic of
adolescents. The social capital scale was adapted from an adolescent
social capital scale used by Gage et al (2005) [4] and showed a
reasonable internal consistency (Cronbach’s Alpha = 0.63) when
tested on Indian adolescents. Social support scale was adapted from
the adolescent social support scale developed by Seidman et al (1995)
[5] and showed excellent internal consistency (Cronbach’s Alpha =
0.86) when tested on study population. Questions on health related
behaviours were taken from WHO HBSC survey which is a survey
of school children undertaken periodically in more than 40 countries
of the world [6].
Results
A social gradient in health inequalities was observed with a
sequentially detrimental health outcome at each lower level of areas
of residence.
Conclusions
The questionnaire was observed sensitive to LMICs setting and
consistent with both international as well as Indian adolescents
context. Studying both clinical and subjective health outcomes
in a population can provide important insights about different
explanations of various indicators of health, highlighting the complex
nature of inequalities. The questionnaire is useful in identifying social
inequalities in health to advance health equity among adolescents.

Developed and validated instruments for urban and culturally diverse adolescents to assess their self-reported transactions with family, peer, school, and neighborhood microsystems for the constructs of social support, daily hassles, and involvement. The sample of 998 youth were from schools in three Eastern cities with high percentages of economically disadvantaged youth. Data were collected before and after the transition to junior high school or to senior high school. Blacks constituted 26%, whites 26%, and Latinos 37% of the sample. Factor analyses confirmed and enhanced the hypothesized four-factor microsystem factor structure for support, hassles, and involvement; internal consistency and stability coefficients were consistent with these structures. In general, the microsystem factors were common across gender, ethnicity, and age. However, when group differences did occur on these demographic variables, they tended to validate the salience of microsystem specificity. In contrast to the total scores, the microsystem-specific factors yielded more meaningful and differential information with regard to demographic differences and the mediating processes across a school transition.

To describe the methodological development of the HBSC survey since its inception and explore methodological tensions that need to be addressed in the ongoing work on this and other large-scale cross-national surveys. Using archival data and conversations with members of the network, we collaboratively analysed our joint understandings of the survey's methodology. We identified four tensions that are likely to be present in upcoming survey cycles: (1) maintaining quality standards against a background of rapid growth, (2) continuous improvement with limited financial resources, (3) accommodating analysis of trends with the need to improve and adapt questionnaire content, and (4) meeting the differing requirements of scientific and policy audiences. While these challenges are not trivial, the structure of the HBSC network and its long-term experience in working through such challenges renders it likely that HBSC can provide a model of other similar studies facing these tensions.

Characterizing school health promotion is its category-by-category approach, in which each separate health-related behavior is addressed independently. Such an approach creates a risk that extra-curricular activities become overloaded, and that teaching staff are distracted by continuous innovations. Within the health promotion sector there are thus increasing calls for an integrative approach to health-related behaviors. However, a meaningful integrative approach to different lifestyles will be possible only if there is some clustering of individual health-related behaviors and if health-related behaviors have a minimum number of determinants in common. This systematic review aims to identify to what extent the four health-related behaviors smoking, alcohol abuse, safe sex and healthy nutrition cluster; and how their determinants are associated. Potentially modifiable determinants that offer clues for an integrative approach of school health-promotion programs are identified. Besides, the direction in which health educators should look for a more efficient instructional design is indicated.

Cities are the predominant mode of living, and the growth in cities is related to the expansion of areas that have concentrated disadvantage. The foreseeable trend is for rising inequities across a wide range of social and health dimensions. Although qualitatively different, this trend exists in both the developed and developing worlds. Improving the health of people in slums will require new analytic frameworks. The social-determinants approach emphasizes the role of factors that operate at multiple levels, including global, national, municipal, and neighborhood levels, in shaping health. This approach suggests that improving living conditions in such arenas as housing, employment, education, equality, quality of living environment, social support, and health services is central to improving the health of urban populations. While social determinant and multilevel perspectives are not uniquely urban, they are transformed when viewed through the characteristics of cities such as size, density, diversity, and complexity. Ameliorating the immediate living conditions in the cities in which people live offers the greatest promise for reducing morbidity, mortality, and disparities in health and for improving quality of life and well being.

The gross inequalities in health that we see within and between countries present a challenge to the world. That there should be a spread of life expectancy of 48 years among countries and 20 years or more within countries is not inevitable. A burgeoning volume of research identifies social factors at the root of much of these inequalities in health. Social determinants are relevant to communicable and non-communicable disease alike. Health status, therefore, should be of concern to policy makers in every sector, not solely those involved in health policy. As a response to this global challenge, WHO is launching a Commission on Social Determinants of Health, which will review the evidence, raise societal debate, and recommend policies with the goal of improving health of the world's most vulnerable people. A major thrust of the Commission is turning public-health knowledge into political action.

Low adult supervision during the after-school hours has been associated with numerous problem behaviors among youth. We examined the extent to which this relationship pertains to the evening hours and aggressive behaviors. Cross-sectional self-report data were obtained from a nationally representative sample of 14,818 youth in grades 6-10 in the 2001-2002 Health Behaviors of School-aged Children Survey. The relationship between spending evenings out with friends and involvement in problem behaviors was examined using logistic regression analyses. One-fifth of U.S. youth surveyed reportedly spent five or more evenings out with friends each week. After adjusting for grade, race/ethnicity, parental education, parental involvement, and perception of neighborhood safety, boys and girls who reported spending five or more evenings out were 4.3 and 3.1 times, respectively, than boys and girls who spent less than two evenings out, more likely to be involved in four or more physical fights in the past year; 3.0 and 4.0 times, respectively, more likely to have bullied another at least once a week at school; 2.7 and 4.9 times, respectively, more likely to have carried a weapon 6 or more days in the past month; 3.8 and 4.8 times, respectively, more likely to consume alcohol at least once a month; and 3.3 and 7.2 times, respectively, more likely to have smoked every day. Although the majority of youth who spend most evenings out do not frequently participate in problem behaviors (69.7%), their consistently increased risk for substance use and aggressive behaviors warrants attention. Further examination of specific evening activities, extracurricular involvement, neighborhood context, adult supervision, and parental monitoring is required.
