ABSTRACT

Poor nutrition and insufficient physical activity contribute to high rates of obesity. Prevalence, intention to change and co-occurrence of four health risk behaviours (inadequate fruit and vegetables, excessive dietary fat, excessive sugary beverages and inadequate physical activity in comparison to public health recommendations) were investigated in an Australian population of working adults. Participants (n=105) completed sociodemographic and stage of change questionnaires. A subsample (n=40) were assessed twice to estimate test-retest repeatability. In the full sample, 73% were female, mean age was 33.8 years and mean BMI was 23.8 kg/m(2). Eighty-seven percent of participants consumed inadequate fruit and vegetables, 43% had excessive dietary fat, 42% had excessive sugary beverages and 29% had inadequate physical activity. The proportions intending to change each behaviour were 57%, 25%, 18% and 24%, respectively. Two-thirds exhibited multiple risk behaviours and 38% intended to change multiple risk behaviours. Fruit and vegetables and dietary fat were the most commonly paired risk behaviours (39%) and the pair most intended to change (19%). Occurrence of multiple risk behaviours was associated with being male (OR 3.10, 95% CI 1.06-9.03) or overweight/obese (OR 2.66, 95% CI 1.02-6.93). Targeting two risk behaviours, particularly fruit and vegetables and dietary fat, may be appropriate when designing health promotion programs in working populations.

    ABSTRACT: A survey regarding dietary intake and physical lifestyle among Residential College Students was conducted in Universiti Kebangsaan Malaysia (UKM). The objectives of study were to determine and evaluate student’s dietary intake and physical lifestyle in the campus which focus to Ungku Omar Residential College, one of the 12 Residential Colleges in UKM. This study was used experimental research design where 100 students (10 percent of population) have been selected randomly through their quotas of race and gender. The results show that the dietary intake of macronutrient carbohydrate, fat and protein taken by the majority of the students (≥50%) have been met the satisfied level as suggested by The Malaysian Food Pyramid Guideline. However, 35-57 percents of student were consuming high calories and high fat food diet. Based on the data obtained, there are relationship between the pattern of students’ dietary intake and quality of services and food inside the campus. According to the students’ perception, the food outlets (cafeteria) in campus were providing balanced diet, but the quality and safety of food and services were still unsatisfied. The result also found that the students were practicing an active lifestyle with moderate outdoor exercise during their campus life. We concluded that the students in Ungku Omar’s Residential College are practicing healthy campus lifestyle with a satisfied level of balanced dietary intake and physical lifestyle. However, further improvements and attention on students’ dietary intake, especially vegetables, fruits, calories and fat intake are necessary. Therefore, the cafeteria and Residential College administration need to monitor and improve the status of dietary and physical lifestyle among students periodically through a constant survey.

    ABSTRACT: AimAlthough the Transtheoretical Model's processes of change have been investigated for improving fruit and vegetable intake in adults, no studies have been conducted in Australia. To help understand what might enable Australian adults to change, we assessed the relationship between stages and processes of change.MethodsA convenience sample of university students and employees (n = 105; female = 77) aged 18–60 years participated in this cross-sectional study. Validated questionnaires that measure stages and processes of change for fruit and vegetable consumption were completed. The process of change questionnaire used 40 items, with responses on a 5-point Likert scale ranging from ‘never’ to ‘repeatedly’.ResultsNinety-eight per cent of the sample was in the precontemplation, preparation or maintenance stage. Most differences in process use occurred between precontemplation and the combined contemplation/preparation stages. This latter displayed higher cognitive (P = 0.001) and behavioural process use (P = 0.01). Individual processes predominantly responsible for these differences were consciousness raising, dramatic relief, self re-evaluation and self liberation.Conclusions While there are limitations regarding study design and population, the results suggest that when designing a program to increase fruit and vegetable intake, targeting these processes may assist participants' progression from precontemplation to preparation. Additional research is necessary to critically examine process use between preparation and maintenance stages.
