Predictive Factors for Future Onset of Reflux Esophagitis: A Longitudinal Case-control Study Using Health Checkup Records.

Background/aims: Although risk factors of reflux esophagitis (RE) have been investigated in numerous cross-sectional studies, little is known about predictive factors associated with future onset of RE. We investigated time courses of clinical parameters before RE onset by a longitudinal case-control study using health checkup records.

Methods: We used health checkup records between April 2004 and March 2014 at 9 institutions in Japan.

Roles of alcohol consumption in fatty liver: a longitudinal study.

Background & Aims: Roles of alcohol consumption in non-alcoholic fatty liver disease are still controversial, although several cross-sectional studies have suggested the beneficial effect of light to moderate drinking on fatty liver. We analyzed the longitudinal relationship between drinking pattern and fatty liver.

Methods: We included 5297 Japanese individuals (3773 men and 1524 women) who underwent a baseline study in 2003 and follow-up at least once from 2004 to 2006.

Possibility of Delay in the Super-Compensation Phase due to Aging in Jump Practice.

Purpose: To investigate the possibility of a delay in the super-compensation phase due to aging in jump practice.

Methods: This study evaluated records in three phases (approximately every five years) of a man who had been participating in Masters Athletics for over 20 years. After correcting for air temperature, which would influence the distance on a standing five-step jump using simple regression analysis, the performance curve of the super-compensation phase was calculated at each phase by curvilinear estimation to assess the relationship between the training interval and distance on the standing five-step jump.

Roles of alcohol drinking pattern in fatty liver in Japanese women.

Purpose: Several studies have reported an inverse association between moderate alcohol consumption and prevalence of fatty liver (FL) in men. We aimed to clarify this association in women.

Methods: We collected health checkup data from 4,921 Japanese women without concurrent liver disease (mean age 46.

Alcohol consumption appears to protect against non-alcoholic fatty liver disease.

Background: Moderate alcohol consumption may have certain beneficial effects against non-alcoholic fatty liver disease, which is associated with metabolic syndrome.

Aim: To determine the association between drinking pattern and fatty liver in Japanese men and women.

Methods: A cross-sectional study was performed with health checkup data including information concerning alcohol consumption and ultrasonographic assessment of fatty liver.

Occupations associated with bullae on chest radiographs in Japanese middle-aged men.

Objectives: To examine an association between occupation and bullae seen on chest radiographs.

Methods: We performed a cross-sectional study of 27,361 men in their 50s who consulted our institute for health screening. Logistic models that independently incorporated occupation, age and smoking as variables in a stepwise fashion were selected.

[Usefulness of exercise electro-cardiography in a THP (Total Health Promotion Plan)].

We conducted ergometer exercise electrocardiography (ergometry) on 3,477 subjects in a THP (Total Health Promotion Plan). One hundred cases in which abnormal findings were detected by ergometry were analyzed. In the hundred cases there were 3 patterns: abnormal ST change, 50 cases; abnormal reaction, 22 cases; and extreme increase in blood pressure, 28 cases.
