(-7 pp.). Participation in school sporting activities reduces the likelihood of being overweight only for students of middle and low SES (-5,5 pp.). For adolescents of high SES, the distance between their school and the nearest fast food restaurant decreases the likelihood of being overweight (-4.7 pp. per km.). Conclusions:The determinants of overweight differ by SES. Public policy design should consider socioeconomic inequalities that characterize the Chilean reality. (Rev Med Chile 2015; 143: 598-605)

Latin American educational policy has relied on the assumption that better preparation can help school leaders improve their professional performance, thus improving quality of schools. Training programs for present or future school leaders have proliferated in the region, often publicly financed, but without enough evidence of their impact. Using data for seven Latin American countries from the Third Regional Comparative and Explanatory Study (TERCE), we seek to determine the association between school leaders’ formal education and training received, with well recognized dimensions of school leadership practices reported by their teachers. We estimated linear regression models for each country in Latin America to determine the relationship between principals’ preparation with indicators of educational leadership practices. Our results show that in most observed indicators of leadership practices the effect of education or training is marginal. We provide possible explanations for this finding, emphasizing the weaknesses in principals’ initial selection processes and their deficiencies. We also consider schools’ precarious conditions to support principals in order to put the knowledge they learned in training activities into practice. We point out the need to continue conducting specific studies on the effects of training on educational leadership among school leaders in the region, overcoming TERCE information restrictions.

The conventional model in which people completely retire from a full-time job at normative ages and the widely promoted new conventional model of late retirement are both associated with better functioning than early labor force disengagement. But unconventional models, where older adults keep partially engaged with the labor force are also significantly associated with better functioning. These findings call attention to more research on potential avenues to simultaneously promote productive engagement and health later in life.
