although evidence supports the importance of lifestyle in promoting health , many people still have unhealthy lifestyles ( 3 ) . with the global changes of social and economic patterns ,
the lifestyle is a collection of attitudes , habits , and desires related to one person or a group ( 5 ) .
healthy lifestyle is defined as the type of lifestyle that provides , preserves , and enhances the level of health and welfare ( 6 ) .
noticing the role of lifestyle in preventing diseases , improving the quality of life , increasing life expectancy , and improving mental and physical health is of paramount importance ( 7 ) .
the patterns of lifestyle are deeply rooted in old habits and affect the person s health in the long term ( 8) .
more than one third of the deaths occur as a result of unhealthy lifestyles worldwide , which are the main cause of developing cardiovascular diseases , hypertension , type 2 diabetes , tooth decay , stroke , and number of cancers ( 9 , 10 ) . nowadays
, lifestyle modification is an important strategy to prevent non communicable diseases ( 11 ) .
the diseases which result from unhealthy lifestyles are the most common causes of mortality and morbidity in iran as well ( 12 ) .
usually people spend one third of their time at their workplaces with conditions that may reinforce keeping away from healthy behaviors ( 13 ) . maintaining
a healthy and productive workforce is essential for employers in public and private sectors ( 14).the health status is one of the most important reasons of premature retirement and decreased capability of the employees . the health status of the employees may deteriorate due to chronic diseases that originate from certain lifestyles .
an unhealthy lifestyle can result in illness , absenteeism , and low productivity of the employees ( 15 ) .
moreover , healthy employees are more productive , are less likely to be absent from work due to illness , and more involved in their duties ( 16 ) .
the current study aimed to evaluate the lifestyle and obesity status of the employees working in public organizations of hamadan , some associated factors , and their position according to trans - theoretical model .
this cross - sectional , descriptive - analytical study was performed on 1200 employees working in the public sectors of hamadan , west of iran , in 2014 .
the inclusion criteria were officially employed , male or female above 18 , more than one year of working experience .
individuals with medical condition such as pregnancy , depression or other serious disease were excluded .
twenty two staff were excluded due to pregnancy ( n = 8) , musculoskeletal disorders ( n = 6 ) and other serious health problems ( n = 8) .
a total of 24551 employees were registered in the governor s office list . according to the results of a prior study in iran ( 17 ) with 80%power in a two - tailed tests at a significance level of 0.05 , determined the sample size for the study at 1200 .
the sampling strategy was based on a proportionate stratified random sampling . the organizations with more than > 50 employees who had agreed to participate in the study were considered as one stratum . considering the sample size ,
participants were met at workplace for a face to face interview by a trained interviewer .
after coordination with the directors of the offices , a questionnaire was distributed among the employees .
the researchers provided the necessary information regarding the questionnaire completion and ethical issues including anonymity of the answers .
offices in this study were certain organizational units established according to the law , with legal independence , executed part of the duties , and responsibilities of one of the three executive , legislative , and judicial systems and other legal organizations .
data were collected through a questionnaire with three sections ( demographic information , fantastic lifestyle questionnaire , and marcus s five part algorithm ) .
the fantastic lifestyle questionnaire was developed by wilson and ciliska in the family medicine department of mcmaster university , canada .
the acronym represents the first letters of the nine domains ( in english ) in which the 25 questions or items are distributed .
questions were coded by points as follows : zero for the first column , 1 for the second,2 for the third,3 for the fourth , and 4 for the fifth column . the total score of fantastic ranges from zero to 100 and higher score indicates a better condition .
according to the total score , the respondents were categorized in five categories : excellent ( 85 - 100 ) , very good ( 70 - 84 ) , good ( 55 - 69 ) , regular ( 35 - 54 ) , and needing improvement ( 0 - 34 ) .
the results were interpreted as follows : " excellent " indicates that the individual s lifestyle represents an optimal influence for health ; " very good " indicates that the lifestyle represents an adequate influence for health ; " good " indicates that the lifestyle represents many benefits for health ; " regular " indicates that the lifestyle represents some benefit for health , although it also poses risks ; " needing improvement " indicates that the individual s lifestyle poses many risk factors . to evaluate the reliability and validity of the questionnaire , it underwent primary translation and re - translation by the author and a number of experts in the field of health education and health promotion .
the experts were requested to evaluate the tool in terms of clarity , readability , face validity and relevance .
the questionnaire was completed by 20 employees twice in a two - week interval and a reliability coefficient of 79% was obtained . to calculate the body mass index ( bmi ) ,
weight was measured with a digital scale ( terraillon ) without shoes with minimal clothing .
the current study employed the trans - theoretical model developed by prochaska and diclemente in 1970 to investigate physical activity , as one of the most important items of lifestyle . in this model
, people are categorized in five categories regarding the levels and stages of change : a ) pre - contemplation : people at this stage do not intend to start the healthy behavior within 6 months ; b ) contemplation : at this stage , participants are intending to start the healthy behavior within the next six months ; c ) preparation : people at this stage are determined to change within the next 30 days and have prepared some means ; d ) action : people at this stage perform the behavior regularly ; and e ) maintenance : people at this stage perform the behavior for more than six months .
the five - part algorithm of marcus was used to evaluate the stages of change .
its reliability and validity in iran were confirmed in two studies by jalilian et al .
the main statistical tests used in the study were linear regression , chi square , fisher exact test , and independent t - tests , and analysis of variance ( anova ) . to assess differences in characteristics ,
linear regression was used to assess the association between bmi and variables such as education level , age and work experience .
ethics committee approval was obtained from the ethics committee of tehran university of medical sciences ( i d : 9021108006 ) .

ethics committee approval was obtained from the ethics committee of tehran university of medical sciences ( i d : 9021108006 ) .
males and females comprised 50.6% ( n = 607 ) and 49.4% ( n = 593 ) of the participants , respectively .
the majority of the employees ( 55.6% ) had bachelor s degrees and 13.2% had higher degrees .
most of the employees ( 81.8% ) were married and had 1.24 offspring on average .
table 1 presents the status of the lifestyle of the employees of iran based on demographic specifications .
one of the employees ( 1% ) had an excellent lifestyle , 21.6% ( n = 259 ) had very good lifestyles , 61.7% ( n = 740 ) had good lifestyles , 16.1% ( n = 193 ) had regular lifestyles , and the lifestyle required improvement in 0.6% ( n = 7 ) of the employees .
there was a significant relationship between the lifestyle and gender , age , work experience , marital status , and income satisfaction ( p < 0.05 ) .
table 2 presents different stages of the trans - theoretical model in the item of physical activity based on gender . according to the results ,
females were in higher stages of change ( action and maintenance ) in the item of physical activity than males . regarding smoking ( at least one cigarette per day ) , 86.8% of the employees did not smoke while 2.8% ( n = 33 ) smoked more than 10 cigarettes a day . regarding cola containing drinks ( coffee , tea , etc . ) , 45.8% ( n = 550 ) drank them once or twice a day , 3.2% ( n = 38 ) drank them more than 10 times a day , and 37.1% ( n = 445 ) drank them 3 - 6 times a day .
the other items of fantastic lifestyle questionnaire are summarized in table 3 . in the current study ,
only 35.5% had moderate - intensity physical activity five times or more per week ( table 4 ) .
the results of the present study showed a significant relationship between bmi and gender , number of offspring , marital status , and work experience ( p < 0.05 ) .
bmi increased in the participants with an increase in work experience , the prevalence of overweight and obesity for married participants was higher than single ones , and the bmi increased with an increase in the number of offspring .
multiple linear regression analysis with stepwise method showed that age and work experience were the strongest predictors of obesity ; they explained of 31.2% variance of obesity ( adjusted r = 0.312 , r change = 0.01 ) .
a healthy lifestyle is a valuable source of decreasing the prevalence and effect of health problems , promoting health , coping with stressors , and improving the quality of life ( 6 , 21 - 23 ) . considering the effective role of employees as valuable human resources in delivering services ,
the current study was conducted to evaluate the lifestyle of the employees working in the public sectors of hamadan and some associated factors using the trans - theoretical model . in the current study ,
determination of the status of the individuals in terms of the stages of health related behaviors is an appropriate reflection of their attitude and performance ; the results can provide basic information to design appropriate educational programs for the designated behavior and thus help to prevent the related diseases and enhance health and well - being in the society ( 24 - 27 ) .
it has a very important role in the prevention of lifestyle related diseases and health promotion , and enhances psychological performance , increases friendly gatherings , improves night s sleep , and is considered an appropriate recreation ( 6 ) .
recent studies have shown that a small percentage of adults are engaged in the recommended levels of physical activity ( 28 ) . in the current study ,
about half of the participants were at the preparation stage , which was compatible with the results of the study by mazlomi ( 29 ) . in a study by haakstad et al .
about 70% of the employees did not have vigorous - physical activity and their moderate - physical activity was not favorable either . in a study by fayaz - bakhsh et al .
( 31 ) , 44.1% of the participants did not exercise at all . the results of a study by pirzadeh showed that 76% of the participants had moderately favorable physical activity ( 32 ) .
limitations in time and place are the most important factors for the lack of physical activity and weight management in employees ( 33 , 34 ) .
the current study found a significant relationship between the lifestyle and age , which was in line with the results of the study by pirzadeh ( 32 ) .
gender has a strong independent effect on the health and disease status , and selection of lifestyles and living habits ( 36 ) .
studies have shown that females use more healthcare services comparing males , but underreport their health status when compared to males ( 37 ) .
the currentstudy found a significant relationship between gender and lifestyle and females had a better status in all items comparing males .
based on trans - theoretical model females were at higher stage of change ( action and maintenance ) than males .
no significant relationship was found between the education and lifestyle , maybe due to the similarity of the educational level in the majority of the employees .
( 32 ) but different from the findings of other studies ( 39 , 40 ) .
income and income satisfaction result in differences in the socioeconomic status of the people in a society . a higher income results in relative well - being and satisfaction which can affect the lifestyle .
there is a confirmed relationship between income and mortality in the literature ( 41 ) .
the family and its composition are key determinants of lifestyle behaviors and married people have a higher quality of life .
one of the consequences of unhealthy lifestyle is weight gain and obesity , which is regarded as the biggest public health problem worldwide by the world health organization ( who ) ( 42 ) .
the relationship between the bmi and lifestyle was significant in the current study , since the increase in bmi was more in those who followed unhealthier lifestyles .
this finding was in line with the results of the studies by pirzadeh in isfahan , iran ( 32 ) and van wier in the netherlands ( 33 ) .
work environment is one of the determinants of health , and employees spend a lot of their time at work .
employees with more years of work experience tend to adopt a more sedentary lifestyle . in the current study ,
it seems that marriage causes some changes in the lifestyle , especially in nutrition and physical activity , which may result in weight gain and obesity .
social support is a protective factor for mental health in adults and especially the elderly ( 43 ) .
health promotion behaviors are observed more frequently in individuals who have strong and positive social support networks ( 36 ) . moreover ,
social support and interpersonal relations are among the most stable health indicators in different studies ( 12 ) .
the current study noted that the employees received favorable social support and the employees had a healthier status in terms of smoking , since 86.8% of them did not smoke .
this finding was similar to the results of the studies by pirzadeh ( 32 ) . in a study by fayaz - bakhsh et al .
about 18.1% of the participants in the current study stated that they always had a balanced diet . in the study conducted by pirzadeh
, 18% of the participants had a moderately favorable nutritional status ( 32 ) . since the status of many items including physical activity and healthy diet of the employees is not favorable , and considering the results of the current study , it is important to plan health education interventions for the employees , focusing on the effective approaches based on behavior change theories like the trans - theoretical model in terms of time and place . regarding the limitations ,
the current study was performed among the employees of the public sectors and the employees working in the private sectors were not included ; moreover , the status of the employees only in one of the items of the lifestyle ( physical activity ) was assessed which could affect the generalizability of the results .

 data were analyzed by spss-20 using linear regression , chi - square , fisher exact test , and anova.results:the mean age of the employees was 38.12  8.04 years . 
 most of the employees ( 61.7% ) had favorable lifestyle . 
 about half of the employees were at the preparation stage of ttm . 
 most of the employees were in a poor condition regarding the physical activity and healthy eating habits . in most of the evaluated items , females got higher scores than males . 
 the associations between lifestyle and age , gender , work experience , income satisfaction , and marital status were significant . moreover , the associations between obesity and work experience , marital status , number of offspring , and gender were significant ( p < 0 . 
 05 ) . 
 significant predicting variables of obesity were age and work experience ; they explained 31.2% variance of obesity ( adjusted r2 = 0.312 , r2 change = 0.01).conclusions : planning health education interventions for employees through effective approaches seems necessary .
