Associations between objectively measured physical activity and later mental health outcomes in children: findings from the UK Millennium Cohort Study.

Background: The beneficial effect of physical activity (PA) on mental health in adults is well established, but less is known about this relationship in children. We examine associations between objectively measured sedentary time, PA and mental health in 11-year-olds from the UK Millennium Cohort Study (MCS).

Methods: Longitudinal data from MCS sweeps 4 (age 7) and 5 (age 11) were used (n=6153).

Factors Associated with Non-disclosure of HIV Status in a Cohort of Childbearing HIV-Positive Women in Ukraine.

Ukraine has one of the largest populations of persons living with HIV in Europe. Data on 2019 HIV-positive married or cohabiting women enrolled in a postnatal cohort from 2007 to 2012 were analysed to investigate prevalence and factors associated with self-reported non-disclosure of HIV status. Median age at enrolment was 27.

Global surveillance of cancer survival 1995-2009: analysis of individual data for 25,676,887 patients from 279 population-based registries in 67 countries (CONCORD-2).

Background: Worldwide data for cancer survival are scarce. We aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the effectiveness of health systems, and to inform global policy on cancer control.

Methods: Individual tumour records were submitted by 279 population-based cancer registries in 67 countries for 25·7 million adults (age 15-99 years) and 75,000 children (age 0-14 years) diagnosed with cancer during 1995-2009 and followed up to Dec 31, 2009, or later.
