The concurrent sampling design was developed for case–control studies of recurrent events. It involves matching for time. Standard conditional logistic-regression (CLR) analysis ignores the dependence among recurrent events. Existing methods for clustered observations for CLR do not fit the complex data structure arising from the concurrent sampling design. Read more at https://academic.oup.com/ij

The Philippine National Nutrition Survey (NNS) is the official nationwide survey on nutritional status, diet and other lifestyle-related risk factors for noncommunicable diseases. The NNS is designated to generate critical data for decision making by the government and the private sector in the Philippines. Data from the NNS have been used as a reference for formulating the Philippine Plan of Acti

The Maule Cohort (MAUCO) is the first prospective population-based cohort of cardiovascular disease (CVD) and cancer in central Chile. The rationale for this cohort is based on the social, environmental and health characteristics of an under-studied rural population at high risk for chronic diseases.

In many resource-constrained settings, availability of reliable vital statistics and health information is limited by lack of proper system for civil registration and health information. This is further limited by the fact that the majority of population health events, such as births, morbidity and mortality, occur outside the reach of these systems. In particular, obtaining credible data from rur

The Finnish Gestational Diabetes (FinnGeDi) study is a multicentre study that considered Finnish women who gave birth in 2009–12, as well as their children and the children’s fathers. The study period was after the introduction of new Finnish national comprehensive screening guidelines for gestational diabetes mellitus (GDM). The study consisted of two arms: a prospective clinical, genetic case-co

Physical activity (PA) may improve brain development, cognition, concentration and academic performance. In this prospective controlled intervention study, we increased the level of PA in 338 children aged 6–8 years at study start, from the Swedish standard of 60 min per week to 200 min per week (40 min daily). The intervention continued in all nine compulsory school years until the students gradu

The objective was to investigate associations between the General Health Questionnaire with twelve sub-items (GHQ-12) and prospective five-year suicide mortality. The two commonly used GHQ-12 cut-offs (2/3 and 3/4) were analyzed. METHOD:The 2008 public health survey, which was conducted in the autumn of 2008 in Scania, southern Sweden, is based on a postal questionnaire answered by 28,198 particip

Preeclampsia is one of the most common causes of perinatal and maternal morbidity/mortality. One suggested environmental risk factor is exposure to endocrine-disrupting pollutants such as per- and polyfluoroalkyl substances (PFAS). The present case-control study in southern Sweden aims to investigate the hypothesized association between serum concentrations of PFAS in early pregnancy and the risk

Although colorectal cancer (CRC) screening guidelines acknowledge the need for earlier screening for high-risk individuals, such as those with family history of CRC, there is limited information on how many years earlier these high-risk individuals should be screened; current practice is based on weak evidence.

Prenatal exposures may contribute to male infertility in adult life, but large-scale epidemiological evidence is still lacking. The Fetal Programming of Semen quality (FEPOS) cohort was founded to provide means to examine if fetal exposures can interfere with fetal reproductive development and ultimately lead to reduced semen quality and reproductive hormone imbalances in young adult men.

We included adults aged 18 years and older in Sweden in first‐generation (n = 6 042 891) and second‐generation (n = 4 860 469) sub‐studies. MS was defined via two diagnoses in the Swedish National Patient Register. MS risk was estimated by Cox regression, with hazard ratios (HRs) and 95% confidence intervals (CI), in different immigrant groups, using Swedish‐born as referents in first‐generation s

Alpha-1 antitrypsin deficiency (AATD) is a rare and underdiagnosed disease that is associated with the development of liver disease in adults and children and pulmonary emphysema in adults. Several studies have shown that there is limited knowledge about the disease and its diagnosis among health care providers, and there is an important inequity in the access to specialized care and appropriate t
