The associations of daily steps and body mass index with incident gastroesophageal reflux disease in older adults.

Background: High body mass index (BMI) is a major risk factor of gastroesophageal reflux disease (GERD), a prevalent morbidity of older adulthood linked to lower quality of life and an increased risk of esophageal cancers. Daily stepping behavior, the most common physical activity of older adulthood, is associated with an array of favorable health outcomes, sometimes independent of high BMI. Whether stepping behavior is associated with the incidence of GERD independently or in combination with BMI is currently unclear.

Increasing Lifestyle Walking by 3000 Steps per Day Reduces Blood Pressure in Sedentary Older Adults with Hypertension: Results from an e-Health Pilot Study.

Increasing daily steps by an additional 3000 steps/day on 5 days/week equates to ~150 min/week of aerobic physical activity to meet the physical activity guidelines; however, its effectiveness for blood pressure control in older adults with hypertension is unknown. A 20-week, single-arm, pilot e-health lifestyle walking intervention was conducted in 21 sedentary older adults (73 ± 5 years old) with hypertension (13 female, 8 male) to investigate the effectiveness of increasing daily steps by an additional 3000 steps/day for blood pressure control. The intervention consisted of two phases, with behavior change assistance provided during the first active phase (weeks 1-10) to help reach step goals and minimal assistance provided during the second self-maintenance phase (weeks 11-20).

Associations of cardiorespiratory fitness and body mass index with incident restrictive spirometry pattern.

Objectives: Restrictive spirometry pattern (RSP) suggests an impairment of lung function associated with a significantly increased risk of premature mortality. We evaluated the independent and joint associations of cardiorespiratory fitness (CRF) and body mass index with incident RSP.

Methods: Data from the Aerobics Centre Longitudinal Study included 12 360 participants (18-82 years).

Associations between cardiorespiratory fitness and diverticulitis in older adults.

Objectives: Examine the independent and joint associations of cardiorespiratory fitness (CRF) and body mass index (BMI) with the prevalence of diverticulitis in older adults.

Methods: 476 older adults (61% Female; 71 ± 5 years) with no history of myocardial infarction, stroke, cancer, inflammatory bowel disease, or diabetes were included in this cross-sectional study. Diverticulitis cases were identified by self-reported physician diagnosis from the medical history questionnaire.

Effect of the COVID-19 Pandemic on Physical Activity and Sedentary Behavior in Older Adults.

Whether the COVID-19 pandemic has long-lasting effects on physical activity (PA) and sedentary behavior in the vulnerable older adult population is uncertain. A total of 387 older adults (75 ± 6 years) completed a retrospective questionnaire on time spent sitting, walking, and performing aerobic and muscle-strengthening PA before, during the first three months, and one year into the COVID-19 pandemic. Whether the participants met the aerobic and muscle-strengthening PA guidelines was then determined.

Association Between Relative Quadriceps Strength and Type 2 Diabetes Mellitus in Older Adults: The Yangpyeong Cohort of the Korean Genome and Epidemiology Study.

Background: To examine the independent and combined association between relative quadriceps strength and the prevalence of type 2 diabetes mellitus (T2DM) in older adults.

Methods: Among 1441 Korean older adults aged ≥65 years (71 [4.7] y) recruited between 2007 and 2016, 1055 older adults with no history of myocardial infarction, stroke, or cancer were included in the analysis.

Associations between relative grip strength and type 2 diabetes mellitus: The Yangpyeong cohort of the Korean genome and epidemiology study.

Objective: To investigate the association between relative grip strength and the prevalence of type 2 diabetes mellitus (T2DM) independently and in combination with body mass index (BMI) in Korean adults.

Methods: The cross-sectional study includes 2,811 men and women (age 40 to 92 years old) with no history of heart disease, stroke, or cancer. Relative grip strength was measured by a handheld dynamometer and calculated by dividing absolute grip strength by body weight.

Associations Between Muscular Strength and Gastroesophageal Reflux Disease in Older Adults.

Background: The association between muscular strength (MS) and prevalent gastroesophageal reflux disease (GERD) in the older adults is not well established.

Methods: This study included 542 older adults with no history of myocardial infarction, stroke, or cancer. MS was measured by handgrip dynamometry.

Effects of core strengthening exercise on colon transit time in young adult women.

Background/objective: This study investigated the effects of core strengthening exercise (CSE) on colon transit time (CTT) in young adult women.

Methods: Eighty women (mean age 23 years) were enrolled and randomly assigned to participate in a 12-week, instructor-led group CSE program (CSE group [CSEG]; n = 40) or to maintain usual daily activities (control group [CG]; n = 40). 27 participants in the CSEG and 21 participants in the CG completed the study.

Results from South Korea's 2018 Report Card on physical activity for children and youth.

Background/objective: is the second comprehensive evaluation of physical activity and the sources of influence based on the 10 core indicators provided by the Active Healthy Kids Global Alliance. It will serve as an advocacy tool to promote physical activity among children and youth.

Methods: Three national surveillance data (i.

Combined exercise improves gastrointestinal motility in psychiatric in patients.

Aim: To examine the effect of combined exercise on colonic transit time (CTT) in admitted psychiatric patients.

Methods: Over a 6-mo period, consecutive in patients with mental illness were recruited from the Somang Hospital Psychiatry Unit. A combined exercise program that included 60 min per day of exercise 3 d per week for 12 wk was performed.

Increase of circulating BDNF levels and its relation to improvement of physical fitness following 12 weeks of combined exercise in chronic patients with schizophrenia: a pilot study.

Brain-derived neurotrophic factor (BDNF), the most abundant of neurotrophins in the brain, is known to be responsible for maintenance of neurons has been implicated in the pathology of schizophrenia. In the present pilot study, we investigated the effect of a combined exercise program on circulating BDNF expression and the relationship between BDNF and improvements in physical fitness. Twenty-four patients with schizophrenia participated in the exercise intervention, three nonconsecutive days per week for 12 weeks.

Comparison of Segmental Colon Transit Time With Total Energy Expenditure in Psychiatry Unit Patients.

Physical activity is associated with a reduced risk of colorectal cancer. We examined the colon transit time (CTT) according to the total energy expenditure (TEE) in psychiatry unit patients. The study participants included 67 adults, with a mean age of 49.

Aerobic exercise improves gastrointestinal motility in psychiatric inpatients.

Aim: To evaluate the benefit of aerobic exercise on colonic transit time (CTT) for psychiatric inpatients in a closed ward.

Methods: Sixty consecutive adult inpatients of the Somang Hospital Psychiatry Unit (Eumsung-gun, South Korea), without CTT-related diseases or drug therapies, were recruited for study from March to June of 2012. Upon enrollment, the patients were randomly assigned to partake in a 12-wk instructor-led group aerobic exercise program (exercise group; n = 30) or to maintain their ordinary daily activities (control group; n = 30).

Colon transit time according to physical activity and characteristics in South Korean adults.

Aim: To investigate factors contributing to the colon transit time (CTT), physical activity and characteristics were examined.

Methods: Forty-seven Korean adults (males, n = 23; females, n = 24) took a capsule containing 20 radio-opaque markers to measure the CTT. The subjects used an accelerometer to measure the physical activity and underwent a bioelectrical impedance analysis to determine the physical characteristics.
