The proposed study will test the hypothesis that frequency of eating away from home meals is independently related to the prospective risk of mortality in the US population. The study will use public-domain mortality linked data from US national Surveys to address this question.
This study uses public domain data collected in the National Health and Nutrition Examination Surveys (NHANES) conducted in 1999-2000, 2001-2002, and 2003-2004 by the National Center for Health Statistics. Data on frequency of eating restaurant meals were collected at that time. The surveys have been linked to the National Death Index and mortality status information is available in public-release files. The investigators aim to examine if exposure to restaurant meals at baseline is prospectively linked to the risk of mortality. All data are anonymized and available in the public domain.
This is an observational study--there is no intervention.

Results from KDOQI guidelines, parathyroid hormone (PTH) level within target range is 150-300pg/ml. Both lower PTH levels and higher PTH levels were associated with higher risk of all-caus...

The role of glycaemic control in the mortality of elderly diabetic patients remains uncertain. GERODIAB is the first multi-centre, prospective, observational study that aims to describe the link betwe...

Anthropogenic greenhouse gas emissions have increased summer temperatures in Spain by nearly one degree Celsius on average between 1980 and 2015. However, little is known about the extent to which the...
Leptin levels may affect mortality through its link to inflammation and obesity. However, data are inconclusive. This meta-analysis was performed to investigate the association of leptin with mortalit...
In randomised controlled trials, men with advanced, non-metastatic prostate cancer (PCa) treated with anti-androgen monotherapy (AA) had similar all-cause mortality as men treated with gonadotropin-re...
A work that reports on the results of a clinical study in which participants may receive diagnostic, therapeutic, or other types of interventions, but the investigator does not assign participants to specific interventions (as in an interventional study).
A study in which observations are made before and after an intervention, both in a group that receives the intervention and in a control group that does not.
A study that uses observations at multiple time points before and after an intervention (the "interruption"), in an attempt to detect whether the intervention has had an effect significantly greater than any underlying trend over time.
A study that compares a group of participants receiving an intervention with a similar group from the past who did not.
A work that reports on the results of a research study to evaluate interventions or exposures on biomedical or health-related outcomes. The two main types of clinical studies are interventional studies (clinical trials) and observational studies. While most clinical studies concern humans, this publication type may be used for clinical veterinary articles meeting the requisites for humans.
