The purpose of this research is to compare two different high altitudes Tibetan group’s physiques, physical strengths and physiological functions. In total 199 Tibetan subjects, 101 subjects (48 males and 53 females) from a 1800 meter highlands (mid-altitude group) and 98 subjects (48 males and 50 females) from a 4000 meter highlands (high altitude group) were examined morphological and physiological characteristics such as height, weight, vital capacity, blood pressure, grip strength and two step exercise test. Subjects for the analyses were extracted from the total subjects by matching the age and sex between the two groups, 53 subjects respectively. Compared to the mid-altitude group, the high altitude group had a smaller body size, lower physical abilities except for endurance performance, lower systolic and diastolic blood pressure and lower vital capacity. The results of vital capacity were different from that of previous researches. Although the blood pressure was remarkably low in high altitude group, it is difficult to attribute the cause only to the difference of altitude, because besides the altitude some differences such as occupations and eating habits existed between the comparison groups.
This study investigated present conditions of people with physical disabilities living in less-populated areas to get basic documents for health promotion activities. We carried out this study in Nanmoku-mura, Gunma Prefecture and in Motegi-machi, Tochigi Prefecture. The main investigation items were as follows : 1) Subjective health, 2) Sense of coherence (SOC), 3) General self-efficacy scale (GSES), 4) The general health questionnaire (GHQ), 5) The relevance among SOC, generalized resistance resources (GRRs), stressors, and health-related index, 7) The relevance between SOC and subjective health, 6) The relevance between SOC and GSES The study subjects were 88 people with disabilities. Mean age (±standard deviation) was 65.0±14.1 years. The average score of SOC was 122.1. Comparing with a manual of GSES, their Self-Efficacy tended “a little low” as a whole. People with severe disabilities tended to think themselves to be unhealthy. Intercommunication with neighbors, and motivations in lives were important to SOC. Limitations of communications, transfers, movements, daily activities owing to disabilities, having housemates or not, and the struggles with the family affected SOC as a stressor while being related mutually. There were positive correlations with healthy behaviors, subjective health, and GSES for SOC. There was negative correlation with GHQ for SOC.
Chronic obstructive pulmonary disease (COPD) is a progressive and chronic lung disease with obstructed lung airflow mainly caused by an inflammatory response. The most common irritant that causes COPD is smoking because of its ability to infringe the whole lung. Breathing the chemical fumes or dusts from the environment also can cause COPD. Dust and sandstorm (DSS) is a serious environmental phenomenon in Northeast Asia. Recently, alkaline DSS adsorb the acid chemicals discharged from the industrial areas of People’s Republic of China (PRC), and the sorbents are considered as a risk factor of the lung disease. In the large city, number of patients visited the respiratory division have increased during the DSS occurrence days. Thus, this study examined the clinical records of the COPD patients admitted to the hospital near the Gobi-Desert in PRC to assess the relationship between the DSS outbreak and the impairment of the lung function. Significantly lowered lung functions and the increased allergic reactions were observed in the people who stayed in the air polluted area and exposed to DSS for a long time. These results suggest that restriction of not only smoking but also DSS inhalation, might be important for the COPD treatment, and the anti-allergic treatment seemed to be effective to suppress the inflammation, especially for the elderly patients.
