[Obesity and diseases in the elderly inpatient]

To explore the obesity distribution in old people and the relation between senile obesity and health.

First, a questionnaire was designed which included chronic disease history, body mass index (BMI), physiological value, biochemistry index, anti-oxidation index, diagnosis of diseases, etc. Second, the measure and detection methods were unified; and the last, the investigation was made along with daily clinical work by clinicians.

We received 391 questionnaires. The overweight rate was 36.1% and the obesity rate was 7.9% . Total anti-oxidation activity in serum (TAS) and superoxide dismutase (SOD) decreased with body mass index (BMI), and the value in the obesity group was the lowest; Malonaldehyde (MDA) of overweight obesity was the largest. The mean blood pressure, blood fat, and blood glucose as well as the prevalence of cardiovascular disease, hyperlipemia, and glycuresis increased with BMI; and the value in the obesity group was the largest.

The prevalence of the senile obesity was below the average and the senile obesity complications were various and serious, and perhaps related to imbalance of free radical's production and cleanup, so the senile obesity seriously harmed old people's health.
