| Abstract: |
| 人类生存与生活离不开自然环境的恩赐与支持。在漫长的历史长河中，由于自然环境的变迁，可使之化利为害，以致发生自然灾害。自然灾害的起因十分复杂，其中包括地质、气象、生物和天文。常见的自然灾害有地震、水灾、旱灾、风灾、海啸、滑坡、泥石流、火山、地下水变异、煤层自燃、瓦斯爆炸等。我国最常见、危及人类生命的灾害有地震、水灾、滑坡、泥石流、瓦斯爆炸等。除火山爆发以外，其他灾害曾多次发生，危害甚大。 |

| Objective To explore the risk factors of hypertension and risk population for adults aged≥25 in the mid-western rural areas of Shandong province and to provide evidence for development of intervention measure. Methods Subjects aged ≥25 were selected by multi-stage stratified random sampling method. All participants were interviewed with a standard questionnaire and physically examined on height, weight, waist circumference, blood pressure and fasting plasma glucose (FPG). Classification tree analysis was employed to determine the risk factors of hypertension and high risk populations related to it. Results The major risk factors of hypertension would include age, abdominal obesity, overweight or obesity, family history and high blood sugar. The major populations at high risk would include populations as: a) being clderly, b) at middle-age but with: high blood sugar or with abdominal obesity/overweight, or with family history, c) people at middle-age but with family history and abdominal obesity. Through classification tree analysis, sensitivity, specificity and overall correct rates were 71.87%, 66.38% and 68.79 %, respectively on ' learning sample' while 70.70 %, 65.84 % and 67.97 % respectively on ' testing sample'. Conclusion Efforts on both weight and blood sugar reduction were common prevention measures for general population. Different kinds of prevention and control measures should be taken according to different risk factors existed in the targeted high-risk population of hypertension. Community-based prevention and control for hypertension measures should be integrated when targeting the population at high risk. |
