Growth response to antiretroviral treatment in HIV-infected children: a cohort study from Lilongwe, Malawi

Objective  Malnutrition is common in HIV-infected children in Africa and an indication for antiretroviral treatment (ART). We examined anthropometric status and response to ART in children treated at a large public-sector clinic in Malawi. Methods  All children aged <15 years who started ART between January 2001 and December 2006 were included and followed until March 2008. Weight and height were measured at regular intervals from 1 year before to 2 years after the start of ART. Sex- and age-standardized z-scores were calculated for weight-for-age (WAZ) and height-for-age (HAZ). Predictors of growth were identified in multivariable mixed-effect models. Results  A total of 497 children started ART and were followed for 972 person-years. Median age (interquartile range; IQR) was 8 years (4–11 years). Most children were underweight (52% of children), stunted (69%), in advanced clinical stages (94% in WHO stages 3 or 4) and had severe immunodeficiency (77%). After starting ART, median (IQR) WAZ and HAZ increased from −2.1 (−2.7 to −1.3) and −2.6 (−3.6 to −1.8) to −1.4 (−2.1 to −0.8) and −1.8 (−2.4 to −1.1) at 24 months, respectively (P < 0.001). In multivariable models, baseline WAZ and HAZ scores were the most important determinants of growth trajectories on ART. Conclusions  Despite a sustained growth response to ART among children remaining on therapy, normal values were not reached. Interventions leading to earlier HIV diagnosis and initiation of treatment could improve growth response.

How Cantonal Education Systems in Switzerland Promote Gender-Typical School-to-Work Transitions

The paper asks how cantonal education systems in Switzerland promote gender-typed school-to-work transitions and gender segregation at work. Data from the Swiss TREE youth panel study is used to analyse the impact of cantonal provision of vocational education and training (VET) on gender-typical educational trajectories. The findings show that education systems with higher VET rates have higher allocations of men in gender-(male-) typical occupational careers. The paper concludes that the pronounced and persistent gender segregation on the Swiss labor market is partly due to a prominent VET system, which urges early gender-typed occupational career decisions.

Parcours scolaires, accès aux études supérieures et mobilité sociale: comparaison entre la France, la Suisse et le Canada

Le présent article examine dans quelle mesure l’organisation des trajectoires scolaires et les parcours conduisant à l’enseignement supérieur favorisent la mobilité sociale ou au contraire la reproduction des inégalités. Nous avons comparé trois pays : la France, la Suisse et le Canada. Les résultats obtenus à partir des données tirées des panels d’enquêtes menées dans ces trois pays permettent d’observer deux situations opposées. Plus l’enseignement supérieur est valorisé au détriment de la formation professionnelle, plus les inégalités d’accès à l’enseignement supérieur ont tendance à s’exacerber. La compétition y est telle que ce sont les jeunes de milieu favorisé qui tirent davantage profit de son expansion. Par contre, lorsque la formation professionnelle est valorisée, les inégalités auraient plutôt tendance à être modérées.
