Objectives: This study aimed to explore the prevalence of low back pain/pelvic pain and related risk factors among a broader population.

Introduction: This study aims to examine the association between provider attributes, including network (patient panel size, degree-number of peer connections, and community size- number of a closely connected group of peers) and individual attributes (travel distance, specialties, and rural practice), and a predominant (most visited) provider.

Methods: This study utilized South Carolina's Medicaid claims data during 2014 to 2018, focusing on live births in hospitals. Samples were limited to pregnant women continuously enrolled in Medicaid throughout pregnancy.

Background: Birthing people in the United States face numerous challenges when accessing adequate prenatal care (PNC), with transportation being a significant obstacle. Nevertheless, previous studies that relied solely on the distance to the nearest provider cannot differentiate the effects of travel burden on provider selection and care utilization. These may exaggerate the degree of inequality in access and fail to capture perceived travel burden.

Background: Using claims data to identify a predominant prenatal care (PNC) provider is not always straightforward, but it is essential for assessing access, cost, and outcomes. Previous algorithms applied plurality (providing the most visits) and majority (providing majority of visits) to identify the predominant provider in primary care setting, but they lacked visit sequence information. This study proposes an algorithm that includes both PNC frequency and sequence information to identify the predominant provider and estimates the percentage of identified predominant providers.

This study examined the incongruence of travel distance between the nearest provider and the provider that pregnant woman actually chose to visit. Using a dataset of South Carolina claims including rural and urban areas for the period 2014-2018 based on live births of 27,290 pregnant women, we compared the travel distance and travel time for two providers of health: the nearest facility and the main one for the area in question. The number of the former type was counted for every case.

Studies have indicated that natural environments have the potential to improve the relationship between a stressful life and psychological well-being and physical health. Forest therapy has recently received widespread attention as a novel solution for stress recovery and health promotion. Bamboo is an important forest type in many countries, especially in East and Southeast Asia and in African countries.

Background: Persistent rural-urban disparities for colorectal and cervical cancers raise concerns regarding access to treatment providers. To the authors knowledge, little is known regarding rural-urban differences in residential proximity to cancer specialists.

Methods: Using the 2018 Physician Compare data concerning physician practice locations and the 2012 to 2016 American Community Survey, the current study estimated the driving distance from each residential zip code tabulation area (ZCTA) centroid to the nearest cancer provider of the following medical specialties involved in treating patients with colorectal and cervical cancer: medical oncology, radiation oncology, surgical oncology, general surgery, gynecological oncology, and colorectal surgery.

Background: The aim of the study was to compare the efficiency of bioelectrical indices (percentage body fat, PBF; visceral fat index, VFI) and various anthropometric measures (body mass index, BMI; waist circumference, WC; waist-to-height ratio, WHtR) on determining hypertension in Chinese.

Methods: We conducted the community-based cross-sectional survey during August of 2013 to August of 2015 in 66 sample sites selected by multistage random sampling method from Henan province. 14,364 residents were included in the study.

This study aims to validate blood pressure (BP) values measured by an oscillometric BP monitor and seek possible calibration methods if discrepancies exist. Noninvasive BP measurement outcomes were determined using an oscillometric BP monitor (Omron HBP-1300) versus a mercury sphygmomanometer (standard device). Two percent of subjects enrolled in an epidemiological investigation were systematically sampled in this study.

Article Synopsis
  • - Genetic studies reveal that susceptibility to esophageal cancer (EC) in families from Xin-an and Xin-xiang counties, China, is significant and contributes to the disease's high incidence.
  • - Analysis of 79 EC families found a heritability rate of 67% among first-degree relatives, suggesting a strong genetic component to the disease.
  • - The research indicates an additive genetic model for EC, advocating for further investigation into the specific genes linked to susceptibility in high-risk populations.
