Introduction: Police officers have a variable work schedule which includes shift
and night work. While some police officers engage in predominantly sedentary
work, others perform work that requires a higher level of physical activity. Shift
work is associated with increased risk of adopting an unhealthy lifestyle, such
as physical inactivity and unfavourable dietary habits. The aim of this study was
to investigate energy balance in Slovenian police officers who engage in pre-
dominantly sedentary work compared to officers who engage in work requir-
ing higher levels of physical activity.
Methods: Fifty-seven Slovenian police officers participated in a regional PROZ-
SIPO project. Participants went through a 10-day objective monitoring of phys-
ical activity with an accelerometer. Dietary intake was also assessed in addition
to body composition and basal metabolic rate. Twenty-nine participants (42.6
± 6.6 years; 23 male, 6 female) were included in the final analysis and further di-
vided into two groups, based on the type of work performed – predominantly
sedentary (n = 12) group or less sedentary (n = 17) group. Descriptive statis-
tics were computed in addition to independent t-test calculation that was used
for between group data comparison.
Results: Total daily energy expenditure (TDEE) was 2972 ± 517 kcal and total
daily energy intake (EI) was 2575 ± 491 kcal. There were no statistically signifi-
cant differences (p > 0.05) in TDEE (2951 ± 626 vs. 2987 ± 445 kcal), EI (2563
± 646 vs. 2583 ± 368 kcal) and energy balance (-390 ± 543 vs. -405 ± 374 kcal)
between groups while the difference in PAL was found to be statistically signif-
icant (1.55 ± 0.02 vs. 1.66 ± 0.03; p = 0.03).
Discussion and conclusion: We found a predominantly negative energy balance
in police officers regardless of their workplace activity. A probable reason for
observed negative energy balance could be underreporting of dietary intake
resulting in lower reported total daily energy intake. The underreporting could
be influenced by social desirability bias in participants further exacerbated by
objective monitoring of physical activity. Further studies should investigate how
to minimize risk of dietary underreporting.
