In the United States (U.S.), currently more than 40% of adults have obesity. This high prevalence presents great concern to demographers because of the potential consequences obesity holds for population health trajectories in morbidity and mortality and individuals' well-being. Primary care providers are critical for managing chronic health conditions, including obesity. This makes it vital to understand whether and how weight shapes primary care use in the U.S. We make this contribution by investigating how obesity is related to annual visits with two of the most common primary healthcare providers used by U.S. men and women- general physicians and gynecologists. Analysis of data from National Health Interview Survey (2010-2018) participants suggests that obesity and overweight are positively associated with annual physician visits among both men and women, with men with class II and III obese having significantly higher odds of annual physician visits than women. In addition, although women with obesity have greater odds of general physician visits than women with normal weight, the former group has lower odds of gynecological visits. This study offers important insights into how obesity positively shapes annual physician visits but negatively shapes gynecological care of women-especially those with class III obesity.
The National Couples' Health and Time Study (NCHAT) is the first fully powered, population-representative study of couples in America containing large samples of sexual, gender, and racial and ethnic diverse individuals. Drawn from the Gallup Panel and the Gallup Recontact Sample, when weighted, the data are population representative of individuals in the United States who (1) are married or cohabiting, (2) are between 20 and 60, (3) speak English or Spanish, and (4) have internet access. The data were collected between September 2020 and April 2021 in the midst of a global pandemic as well as racial and political upheaval. NCHAT includes surveys of 3,642 main respondents and 1,515 partners along with time diaries. We describe the sampling process, challenges weighting a diverse population-representative samples, and sociodemographic characteristics of the NCHAT study. These data will provide opportunities for new research on the health and well-being of American families.
