Impact of diet and life habit on the prevalence of hyperlipidemia in a certain naval unit

Objective To investigate the mpact of diet and life habit on the prevalence of hyperlipidemia in naval personnel. Methods An epidemiological survey was made among the active naval personnel of a certain unit by questionnaire and fasting blood lipid was detected in the naval personnel. The naval personnel with hyperlipidemia were designated as the hyperlipidemia group and those with normal blood lipid were designated as the control group. Then, differences in diet and life habbit were compared between the naval personnel of the 2 groups. Results In the 5 972 naval personnel surveyed, the prevalence of hyperlipidemia was 27.51%. The rate of having high fat diet was more than 2 meals per day in the hyperlipidemia group, accounting for 35.61%, the rate of having high protein diet was more than 2 meals per day, accounting for 79.98%, the rate of preferring sweet diet was 44.74% and the rate of having snacks was more than 3 days per week, accounting for 59.97%. There was obvious statistical significance, as compared with the control group ( P<0.05). For the hyperlipidemia group, the rate of having rich dietary fiber food was more than 2 days per week, accounting for 34.02% and the rate of having rich vitamin food was less than 1 meal a day, accounting for 49.23%, and there was statistical significance, when compared with those of the control group ( P<0.05). For the hyperlipidemia group, the rate of having physical activity was less than 2 days per week, accounting for 39.74%, and total physical activity time was more than 4 hours per week, accounting for 34.57%. There was statistical significance, as compared with the control group (P<0.05). The rate of BMI larger than 24 in the hyperlipidemia group was 39.62%, while that of the control group was just 14.02%, and statistical significance could be found, when comparisons were made between the 2 groups (P<0.05). Conclusion Diet and life habit have significant impact on the prevalence of hyperlipidemia in the naval personnel, to which great emphasis should be paid.
