 Background

Fruit and vegetables (F&V) are strongly associated with health. The latest Swedish national dietary survey from a decade ago showed that consumption of F&V was below recommended levels. However, current consumption in different subgroups is not well known. 

Objective

To investigate the consumption of various F&V types in Swedish adults grouped according to sociodemographic factors and self-reported physical activity (PA).

Design

A cross-sectional survey using a quantitative pen-and-paper or web-based questionnaire in a population-based random sample of adults 18–84 years (final n=1,304; 51%). A self-administered 24-h recall and a food frequency questionnaire (FFQ) were used to measure F&V consumption. Data on gender, age, education level, country of birth, and PA (hours/week) were included as grouping variables. Besides descriptive data, two-sample t-tests and non-parametric tests were performed. A P-value <0.01 was regarded as significant.

Results

Mean F&V consumption based on the self-administered 24-h recall was close to the recommended five portions/day: 5.4 (99% CI 5.1–5.6) portions/day among women and 4.7 (4.4–5.0) portions/day among men (P<0.001). Also the FFQ showed that women generally consumed more F&V than men did. Consumption was lowest among respondents with ≤ 0.5 h self-reported PA/week (P≤0.001), as well as among men born in Sweden (P=0.006). F&V were consumed in almost equal amounts, and fresh F&V were most popular. Intake of berries and cooked F&V was relatively low.

Conclusion

The present study shows a relatively high F&V consumption close to the recommended five portions per day. Gender differences still exist. Also PA and country of birth were significantly associated with F&V consumption.

Abstract [en]

The aim of this thesis was to investigate fruit and vegetable (F&V) consumption among Swedish adults and to use F&V-related perceptions for audience segmentation. Further, the aim was to identify motives and approaches of F&V bloggers, as well as to analyze F&V-related online discourses.

F&V consumption and related perceptions were surveyed using a questionnaire among a random sample of Swedish adults (18-84y; final response rate 51%; n=1 304). F&V consumption was measured using a self-administered pre-coded 24-h recall and FFQ. The average consumption was close to the recommendations. Women in general and men born outside Sweden as well as the physically active respondents consumed the most F&V. The respondents were divided into two clusters based on their F&V-related perceptions. Positive cluster with more women and higher mean age consumed more F&V, whereas Indifferent cluster experienced more practical, habitual as well as external problems with F&V consumption. Cluster analysis is an example of audience segmentation for communicative purposes.

A sample of 50 lay-people blogs with F&V-related content were analyzed with a qualitative content analysis. Two-dimensional categories – level of dietary influential purpose and source of experience – were used to identify blogger ideal types. Exhibitionist with a passive level of dietary influence and lived experiences was the most common type. Persuaders use lived experiences to actively influence their readers, whereas Authorities try to influence mediating others’ experiences. The Mediator is described as a neutral observer. Understanding the role of blogs in everyday communication is important for targeting health messages. A critical discourse analysis was applied to Persuader bloggers’ texts (n=12). Three F&V-related discourses were identified: normative consumption, authentic consumption and altruistic consumption. This analysis is useful for the last process of dietetic communication, namely tailoring the messages.

The present four studies approach dietetic communication processes from a research perspective. However, a further step might be to apply these to a health promotion initiative starting from an identified diet-related problem (e.g. low F&V consumption) through audience segmentation (e.g. through cluster analysis) and targeting a relevant channel (e.g. through blogs) finally to tailor the message (e.g. findings from discourse analysis).
