Abstract. Obesity, as a chronic noncommunicable disease with an
increasing prevalence, and as a risk factor for the development of many
other diseases, represents a serious health problem. Therefore, study
of
risk factors for development of obesity among workers is necessary for
timely prevention this serious public health problem. The purpose of
this
study was: to establish relationship between the eating frequency and
weight
gain; to investigate the portion sizes as a possible causative factor
for
weight gain and to determine the most optimal population education
strategies
for preventive activities in workers.The research included 144 males,
between
20 and 58 years, randomly chosen among workers of the Electronic
Industry,
Niš. The data concerning the number of meals has been obtained by
nutrition
survey. Body mass (kg) and height (m) were assessed by standard methods
and the degree of nutrition has been determined by body mass index
calculation
(kg/m2). The existence of statistically significant difference between
average number of daily meals, weight of daily meals and body mass
index
was examined by means of T-test. The average number of daily meals was
statistically significantly greater in workers with body mass index
less
than 25 kg/m2, compared to subjects with obesity and persons who were
overweight
(T=2.55; P<0.05). Between average differences of daily meals
weights,
in subjects with obesity and overweight subjects compared to other
subjects
with normal body mass, no statistically significant difference had been
found (T=0.63; p>0.05). We concluded that increased eating frequency
is
important for decreasing risk for development of obesity among workers.
Portion sizes had smaller importance for development obesity in this
population.

OBROKA
KAO FAKTOR RIZIKA ZA RAZVOJ GOJAZNOSTI KOD
RADNIKA
Gojaznost kao hronična nezarazna bolest sa rastućom prevalencom, i kao
faktor rizika za nastanak mnogih drugih bolesti, predstavlja ozbiljan
javno
zdravstveni problem. Zato je neophodno ispitati faktore rizika koji
mogu
delovati promotivno i povećati rizik za nastanak gojaznosti kod
različitih
populacionih grupa.
Cilj ovoga rada je bio ispitivanje međuzavisnosti između broja dnevnih
obroka, težine prosečnog celodnevnog obroka, i stepena ishranjenosti
radnika.
Ispitivanjem je bilo obuhvaćeno 144 osoba muškog pola, starosti od
20 do 58 godina, odabranih metodom slučajnog uzorka medju radnicima
Elektronske
industrije u Nišu. Podaci o broju dnevnih obroka i težini celodnevnog
obroka
dobijeni su anketom 24h-ne dijete po sećanju. Telesna masa (kg) i
telesna
visina (m) merene su standardnim metodama, a stanje ishranjenosti
procenjivano
je određivanjem indeksa telesne mase (kg/m2). Pomoću T- testa za velike
nezavisne uzorke je ispitano postojanje statistički značajne razlike
između
prosečnog broja dnevnih obroka, težine celodnevnog obroka i indeksa
telesne
mase.
Prosečan broj dnevnih obroka statistički je bio značajno veći, kod
ispitanika čiji je indeks telesne mase bio manji od 25 kg/m2, u odnosu
na gojazne ispitanike i osobe koje su imale prekomernu telesnu masu
(preko
25 kg/m2) (T=2,55; p<0,05). Između prosečnih težina celodnevnih
obroka,
kod gojaznih i ispitanika sa prekomernom telesnom masom u odnosu na
osobe
sa normalnom telesnom masom, nije nađena statistički značajna razlika (
T=0,63; p>0,05).
Može se reći da povećan broj obroka predstavlja faktor rizika za
nastanak
gojaznosti kod radnika, dok veličina porcije obroka ima manji značaj.
Ključne reči: radnici, broj dnevnih obroka, težina obroka,
gojaznost.
