To examine the potential efficacy of a brief telephone-based parental intervention in increasing fruit and vegetable consumption in children aged 3–5 years and to examine the feasibility of intervention delivery and acceptability to parents.

A pre–post study design with no comparison group. Telephone surveys were conducted approximately 1 week before and following intervention delivery.

Participants were recruited through pre-schools in the Hunter region, New South Wales, Australia.

Thirty-four parents of 3–5-year-olds received four 30-min interventional telephone calls over 4 weeks administered by trained telephone interviewers. The scripted support calls focused on fruit and vegetable availability and accessibility within the home, parental role modelling of fruit and vegetable consumption and on implementing supportive family eating routines.

Following the intervention, the frequency and variety of fruit and vegetable consumption increased (P = 0·027), as measured by a subscale of the children's dietary questionnaire. The intervention was feasible to be delivered to parents, as all participants who started the intervention completed all four calls, and all aspects of the interventional calls, including the number, length, content, format and relevance, were considered acceptable by more than 90 % of parents.

A brief telephone-based parental intervention to encourage fruit and vegetable consumption in pre-school-aged children may be effective, feasible and acceptable. Further investigation is warranted in a randomised controlled trial.

To compare the Household Food Insecurity Access Scale (HFIAS), the US Food Security Survey Module (US FSSM) and a modified version of the US FSSM in which references to buying food were changed to references to getting food, in terms of their classification of food security levels among homeless individuals, and to determine which of these instruments was most preferred by homeless individuals.

A cross-sectional survey.

Recruitment of participants took place at seven shelters and from three drop-in programmes that serve homeless individuals in Toronto, Canada.

Fifty individuals who were ≥18 years of age, able to communicate in English and currently homeless.

The modified US FSSM assigned 20 % of participants to a lower ordinal food security category compared with the US FSSM, and only 8 % to a higher food security category. The HFIAS assigned 30 % of participants to a lower food security category compared with either the US FSSM or the modified US FSSM, and only 10–16 % of participants to a higher food security category. When asked to compare all three instruments, the majority of respondents (62 %) selected the HFIAS as the best instrument for people who are homeless.

A majority of homeless individuals selected the HFIAS as the best food security instrument for people who are homeless. Our findings suggest that the HFIAS is a more appropriate instrument than the US FSSM for measuring food security in the homeless population.

To describe patterns of food consumption associated with overweight/ obesity (OW/OB) and their links to socio-economic status (SES) and urbanization.

A nationwide cross-sectional survey.

Secondary schools in cities, towns and villages in Botswana, Africa.

A total of 746 adolescent schoolchildren.

OW/OB is associated with greater SES, city residence and a snack-food diet pattern. Students belonging to higher SES compared with those from a lower SES background reported significantly (P < 0·01) more daily servings of snack foods (1·55 v. 0·76) and fewer servings of traditional diet foods (0·99 v. 1·68) and also reported that they ate meals outside the home more often (90 % v. 72 %). Students in cities ate significantly (P < 0·01) more servings of snacks (1·69 v. 1·05 v. 0·51) and fewer servings of traditional foods (0·67 v. 1·52 v. 1·61) compared with those in urban and rural villages. The odds of OW/OB were increased 1·16-fold with a snack-food diet, a result that was diminished when controlled for SES.

These data suggest that nutritional transition occurs at different rates across urbanization and SES levels in Botswana. In cities, increasing the availability of fruit while reducing access to or portion sizes of snack items is important. Emphasis on continued intake of traditional foods may also be helpful as rural areas undergo economic and infrastructural development.
