Body mass index in a group of security forces (policemen). Cross-sectional study

Generally, police work is considered a dangerous activity so their health should be taken with the seriousness it deserves, remembering that health is the complete physical, social and mental wellbeing and not just the absence of disease. In all countries, the police play a role of primary importance to ensure the social stability required for the healthy development of society itself. This staff, when doing a speci ic job, has a high prevalence of obesity that is related to hypertension, hyperlipidemia, smoking and a sedentary lifestyle [1].


Introduction
Generally, police work is considered a dangerous activity so their health should be taken with the seriousness it deserves, remembering that health is the complete physical, social and mental wellbeing and not just the absence of disease. In all countries, the police play a role of primary importance to ensure the social stability required for the healthy development of society itself. This staff, when doing a speci ic job, has a high prevalence of obesity that is related to hypertension, hyperlipidemia, smoking and a sedentary lifestyle [1].
Most police of icers work long hours in day and night shifts and this exposure can harm your health. Adverse effects of this occupation include circadian rhythm disorders, inadequate sleep, psychological disorders, metabolic diseases, type 2 diabetes mellitus and heart disease [2].

Material and Method
To know the degree of overweight/obesity in a population of 1000 municipal police of icers, characterized by poor eating habits, lack of physical activities, harmful habits for health such as smoking and alcoholism, as well as variable work schedules of 12 and 24 continuous hours. A cross-sectional study was carried out in a sample of 75 individuals in a routine physical examination and the variables of sex, age, weight (kg), and height (cm) were handled, with these data the Body Mass Index was calculated (IMC) with a free internet application and blood pressure collection with Nebucor electronic equipment. Descriptive statistics was used.

Discussion
Obesity is a prevalent disease throughout the world and can be considered a public health problem among individuals of different occupations, including police of icers who are responsible for public safety. Obese workers are prone to illness, lack of work, disability and early retirement when compared to non-obese workers [3].
Obesity can be a predictor of early mortality; therefore, with a BMI of 30-35, life expectancy decreases from 2 to 4 years and with a BMI of 40-45 this expectation is reduced from 8 to 10 years. Police of icers tend to consume a high-fat diet and the decrease in their physical activity is responsible for high levels of occupational stress [4]. In our study it was found that 70 (93.3%) policemen were overweight and obese BMI>25). In a study by [5] found 85% of overweight and obesity in retired policemen. The current trend is the decrease of physical activity in this work group in such a way that in the study of [6] 9% of the agents rarely exercised, 38% did it 1 to 2 days a day.
week, 32% did it 3 to 4 days a week and only 21% did it 5 days or more a week. The night shift may favor harmful eating behaviors and consequently obesity among the of icers when consuming too many calories through the intake of junk foods (snaks) [7].  In another study by [8] in traf ic agents found hyperlipidemia in 53.7%, hyperuricemia in 46.5% and overweight / obesity in 43.4%, well below what was found in this study regarding overweight / obesity. So they recommend periodic. Medical exams with the aim of promoting the health of these workers. It has also been proven that adiposity can lead to depressive states when associated with work stress [9]. Similarly, Garbarino S, [10] recommends that workers with night shifts and to avoid loss of sleep, high levels of stress and fatigue, which can lead to human errors, incidents and accidents, can have a nap between 30 to 90 minutes before starting their night work.
On the other hand, although sleep disorders are common, they can remain undiagnosed and if they are not taken care of they can adversely affect the health and safety of the police agents and also put the public at risk [11]. Found in a group of North American policemen that sleep disorders were common and were signi icantly associated with their health status, their performance and their own safety [12]. Report that central adiposity is related to heart disease and alcohol consumption, which in itself is a risk factor for these diseases [13]. Studied 7 behavioral variables that could be associated with obesity in police of icers: cardiovascular physical activity, strength training, extension training, sleep hours, alcohol consumption, fruits, vegetables and snacks (snacks: foods rich in fat, sugar and salt) and 6 non-behavioral variables: age, health problems, family support, work hours, work stress and police support, inding a range of obesity in men of 41.9% similar to other studies , but higher than in the general US population 35.5%. In such a way that they recommend equipment for cardio exercise such as treadmills, stationary bicycles, elliptical trainers, and strength training (weights). But if space is not enough passes could be given for private gyms, hiking, golf courses, bowling, roller skating, etc., baseball, basketball, and volleyball teams can also be organized for competitions with community teams, as well as incentives for all participating personnel such as bonuses, vouchers, days off or extra vacations [14]. Recommend physical-recreational activities based on the maintenance and development of the physical condition of the police of icers because they found that with their application there was improvement in resistance in 1.8%, speed 29.8%, swimming 1.6%, strength abdominal 27.8%, BMI 1.5%. Therefore, its usefulness is evident [15]. In their systematic review, found very few studies related to this working group, non-experimental, qualitative at the national level and quantitative at the international level, for which they recommend that more research be carried out in security work groups because of the degree of exposure to which they are exposed.

Conclusions
The indings of this study suggest the implementation of various programs to improve the health of this work group with a multidisciplinary team of doctors, nutritionists, psychologists, and physical trainer, as well as the facilities of adequate physical spaces for the practice of corresponding activities. Of the eight agents with hypertension, six presented obesity which relates overweight to high blood pressure.
