The National Health and Nutrition Examination Survey (NHANES) is a program of the National Center for Health Statistics that began in 1960. The objective of the NHANES is to assess the health and nutritional status of individuals in the United States. The NHANES is a cross-sectional collection of surveys and other health examination data for a nationally representative sample of the resident, civilian, non-institutionalized US population with approximately 5,000 individuals sampled each year [51,52]. We used data from 2015 to 2016 in our study for 5,134 individuals. The inclusion criteria for our study was having a recorded PHQ-9 total score and being 18 or older.
Perception, Planning, and Scoping, Problem Formulation, and Hazard Identification
Published in Ted W. Simon, Environmental Risk Assessment, 2019
In the United States, the Centers for Disease Control (CDC) conducts the National Health and Nutrition Examination Survey (NHANES) with the National Center for Health Statistics (NCHS). NHANES data are available at the CDC’s website, and include results from questionnaires, physical measurements such as height and weight, and measurements of hematological parameters and levels of various chemicals in blood. NHANES uses statistical sampling methods to ensure that the data are representative of the entire US population.86 For example, NHANES includes measurements of more than 200 environmental chemicals, including mercury in hair and blood, lead in blood, as well as dioxin-like chemicals, perfluorinated compounds, and volatile organic compounds in blood.

The prevalence of obesity continues to rise globally. Based on the body mass index (BMI) calculated from measured heights and weights, the 2013–2014 National Health and Nutrition Examination Survey (NHANES) noted the prevalence of obesity (BMI of 30.0 kg/m2 or greater) and class III obesity (BMI of 40.0 kg/m2 or greater) in adults to be 37.7% and 7.7%, respectively.1 Previous NHANES surveys were conducted about every four years with at least one year between survey periods. Beginning in 1999, NHANES became a continuous survey. There was a significant increase in obesity prevalence in adults from 1999–2000 to 2013–2014; however, the increase from 2011–2012 to 2013–2014 was not significant (National Health and Nutrition Examination Survey January 2016. https://www.cdc.gov/nchs/data/factsheets/factsheet_nhanes.htm). The World Health Organization (WHO) estimates that over 600 million adults had obesity in 2014 and the prevalence of obesity more than doubled from 1980 to 2014 worldwide. Most importantly, WHO warns that in most countries obesity kills more than underweight (http://www.who.int/mediacentre/factsheets/fs311/en/). Obesity prevalence is estimated to increase up to 20% in adults by 2025.2

We analyzed data from two cycles of NHANES 1999–2000 and 2001–2002, a series of nationwide, complex, multistage, and probabilistic sampling design surveys designed to assess U.S. civilians’ health and nutritional status conducted by the National Center for Health Statistics (NCHS). Anonymous data can be obtained publicly from https://www.cdc.gov/nchs/nhanes/index.htm. We linked the data with Public-use Linked Mortality Files (https://www.cdc.gov/nchs/data-linkage/mortality.htm) for follow-up mortality data through 13 December 2015. The survey was conducted in the Mobile Examination Center (MEC) including face-to-face interviews, physical examinations and laboratory tests. Participants aged 60 years and older with dietary fibre intake data and cognitive test (n = 2595) were enrolled in the study. A total of 2012 participants were finally involved into the analysis cohort after excluding those with missing covariates. The NCHS Ethics Review Board approved the study protocol (https://www.cdc.gov/nchs/nhanes/irba98.htm), and all participants provided informed consent.

The National Health and Nutrition Examination Survey (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The NHANES 2007–2008, 2009–2010, 2011–2012, and 2013–2014 cohorts were used, and middle-aged adults with and without functional disabilities between the ages of 40 and 64 years were included. We included participants that had complete data for (1) demographic and anthropometric information; (2) valid questionnaire data pertaining to disability and chronic disease diagnoses (e.g., diabetes); and (3) the necessary examination and laboratory assessments of cardiometabolic disease risk factors. Since the data used in this investigation are publicly available and de-identified, this study was deemed to be Not Regulated research, and thus was exempt from full Institutional Review Board review. Original ethical approval was obtained through the National Center for Health Statistics (NCHS) Research Ethics Review Board (Protocol #2011-17). All procedures followed were in accordance with the ethical standards of the NCHS Research Ethics Review Board, and with the Helsinki Declaration, and informed consent was obtained from all patients included in the study.

This was a descriptive, cross-sectional study. Data were extracted from the National Health and Nutrition Examination Survey (NHANES), an ongoing program designed to assess the health and nutritional status of adults and children in the United States, conducted by the Centers for Disease Control and Prevention (CDC). Every year, NHANES data are collected using questionnaire-based interviews, physical examinations, and laboratory tests from a nationally representative sample of about 5,000 residents; data are released on a biennial basis. This study was based on the 2003 to 2006 NHANES databases as these were the only cycles with objectively measured physical activity released at the time of writing. These two cycles included 20,470 children and adults. The NHANES protocol was approved by the National Center for Statistics institutional review board, and written consents were obtained from all participants. Further information on NHANES methodology, data collection, and how to access data are available on the NHANES website (http://www.cdc.gov/nchs/nhanes.htm).
