AbstractObjective:Many public health campaigns encourage increased fibre consumption, but short-term studies suggest that various components of dietary fibre inhibit the absorption of certain micronutrients including carotenoids. These do not take into account long-term adaptation to nutrient intake levels. We aimed to investigate the effect of non-starch polysaccharide (NSP) fibre on plasma micronutrient concentrations in a large free-living population consuming their usual diet.Design:Prospective cohort study. Semi-weighed 4-day food diaries were analysed for micronutrient and NSP fibre intakes. Blood samples were taken and analysed for carotenoids, vitamin A, vitamin E, thiamine, riboflavin, vitamin B6, vitamin B12, folic acid, vitamin C and trace metals.Setting:Participants in a large national cohort study who lived within 30 miles of Leeds.Subjects:Two hundred and eighty-three middle-aged women.Results:The association between NSP intake and plasma nutrient concentrations was assessed taking into account nutrient intakes and other dietary and lifestyle factors. Higher levels of NSP were not associated with lower plasma concentrations of the micronutrients measured, even allowing for the higher nutrient levels generally found in high-fibre foods.Conclusions:Amongst middle-aged women we have shown that current guidelines for increasing the population's NSP consumption can be safely applied. Such guidelines are unlikely to reduce serum micronutrient concentrations, although other, more vulnerable population groups may benefit from further investigation.

Previous research concerning the effectiveness of public health campaigns have explored the impact of message design, message content, communication channel choice and other aspects of such campaigns. Meta analyses reported in the literature reveal, however, that the choice of endorsers in health campaigns remains unexplored. The present study addresses this gap in the literature by studying what makes doctors from public health campaigns appear trustworthy in the eyes of the receiver. The present research examines propensity for trust as well facets of trustworthiness of such expert doctors based on a survey carried out in the UK (155 respondents). Underlying factors of trustworthiness are explored to gain more insight into the understanding of how trust may affect the public’s belief updating and the formation of intentions. Exploratory factor analyses suggest four dimensions of trustworthiness. Multiple regression analyses demonstrate that these factors explain almost 70% of the variance in the participants’ expressed trust in doctors from public health campaigns. Doctors’ ethical stance and their care for the health of the general population appear to be more important for perceived trustworthiness than their actual professional background, although their abilities and competences are closely related to ethics and benevolence. For policy makers this has important implications when selecting endorsers for public health campaigns in order to design effective health related communication, for example to combat obesity.

BackgroundStanding is often classified as light-intensity physical activity, with potential health benefits compared with sitting. Standing is, however, rarely captured as an independent activity. To better understand free-living standing behaviour at a population level, we incorporated a gold standard postural allocation technique into a national cohort study.MethodsParticipants (n=5412, aged 46.8±0.7 years) from the 1970 British Cohort Study were fitted with a water-proofed thigh-mounted accelerometer device (activPAL3 micro) worn 24 hours continuously over 7 days (90.7% provided at least 3 full days). We examined the correlates of free-living standing during waking hours.ResultsTotal daily standing time averaged 4.6±1.5 h/d, accounting for 29% of waking hours, which was largely (98.7%) accumulated in bouts lasting less than 30 min. In mutually adjusted models, male sex, obesity, diabetes, professional occupation, poor self-rated health and disability were associated with lower device-measured standing times.ConclusionMiddle-aged people in Britain spent a surprisingly large proportion of the day in activities involving standing. Standing merits attention as a health-related posture and may represent a potential target for public health intervention.
