Testing, Inequities and Vulnerability of Adolescents to Sexually Transmitted Infections.

Sexually transmitted infections (STIs) should form part of the comprehensive healthcare agenda for adolescents and young people (A&Y) and testing plays a strategic role in STI prevention. However, little attention has been paid to the social and programmatic obstacles to this practice among A&Y. The aim of this study is to describe the prevalence of testing for syphilis and HIV reported by a group of A&Y, analyzing its relationship with variables potentially indicative of inequities related to vulnerability to STIs. This was a cross-sectional survey applied to students at public high schools in three cities in the state of São Paulo, Brazil. The responses of 369 young people who reported having started sexual life were analyzed. The analysis included description of the frequencies of demographic and socioeconomic variables and their associations with testing for syphilis and HIV through the chi-square test. The concentration index (CI) was also calculated, with construction of the respective concentration curve for the associated variables. Positive associations were found between occurrence of testing and living in homes with up to three inhabitants, living in a marital situation with a regular or committed partnership, previous use of primary care services and previous use of hospitals or emergency services. The concentration curve for testing STIs showed significant contributions from the associated variables. The findings indicated that situations of inequity need to be addressed in order to reduce A&Y's vulnerability to STIs.

Scientific literature on food and nutrition security in primary health care: A scoping review.

There is a growing interest in the scientific community regarding Primary Health Care practices aiming at assessing and addressing Food and Nutrition Security. The focus is usually on outcomes, instruments and effectiveness, with no concern regarding theories or concepts. We aimed to map the theoretical frameworks regarding practices towards Food and Nutrition Security in Primary Health Care and describe its conceptualisations based on Ludwik Fleck's epistemological approach. We conducted a scoping review, including 14 databases. Within the 56 publications, the notion of Food and Nutrition Insecurity as a risk for health without further theorisations predominates. Other two minor theoretical frameworks coexist: Food and Nutrition Security as a social determinant of health and as the realisation of a human right. Few publications present Food and Nutrition Security conceptualisations. Of those who define it, there is great variability in the content and sources used. The most elaborated and homogenous conceptualisations are in the human rights group. This review exposes how the disputes surrounding a concept mostly built on policy and international relations penetrate the scientific field. When studying topics in the interface between science and health practices, notably those where controversies exist, researchers should explicitly express their theoretical and conceptual backgrounds.
