Influence of grandparents on the dietary intake of their 2-12-year-old grandchildren: A systematic review.

AIM: Grandparents are assuming increased child-caregiving responsibilities, which potentially influences the dietary intake of grandchildren. The aim of this systematic review is to determine the influence of grandparental care on the dietary intake, food-related behaviours, food choices and weight status of their preschool and school-aged grandchildren. METHODS: Six electronic health databases were searched in January 2017. Inclusion criteria were publication in English language, peer-reviewed journal between 2000 and 2017; children aged 2-12 years; study outcomes included child dietary intake/weight status, grandparent nutrition knowledge/beliefs or grandparent/parent feeding practices. Included studies were appraised for quality and bias. The review was registered with PROSPERO, number CRD42016047518. RESULTS: Sixteen studies were identified in the review, published between 2007 and 2016, with 15 assessed as moderate or high quality. Nine studies reported grandparental child feeding attitudes and behaviours that are considered to negatively influence child dietary intake, while three studies identified positive influences. Seven studies identified that differences in child feeding attitudes and behaviours between parents and grandparents created conflict and tensions between caregivers, often resulting in poor feeding practices. Statistically significant positive associations (odds ratio 1.47-1.72) between grandparent cohabitation and increased rates of child overweight and obesity were found in four studies. CONCLUSIONS: Grandparents in caregiving roles may negatively influence the dietary intake and weight status of their grandchildren. More rigorous, targeted studies are required to further define the mechanisms by which grandparents' knowledge, attitudes and feeding behaviours may influence child dietary intake. This review suggests that grandparents may be an important audience to target in future child nutrition interventions.

Harnessing the power of advertising to prevent childhood obesity.

BACKGROUND: Social marketing integrates communication campaigns with behavioural and environmental change strategies. Childhood obesity programs could benefit significantly from social marketing but communication campaigns on this issue tend to be stand-alone. METHODS: A large-scale multi-setting child obesity prevention program was implemented in the Hunter New England (HNE) region of New South Wales (NSW), Australia from 2005-2010. The program included a series of communication campaigns promoting the program and its key messages: drinking water; getting physically active and; eating more vegetables and fruit. Pre-post telephone surveys (n = 9) were undertaken to evaluate awareness of the campaigns among parents of children aged 2-15 years using repeat cross-sections of randomly selected cohorts. A total of 1,367 parents (HNE = 748, NSW = 619) participated. RESULTS: At each survey post baseline, HNE parents were significantly more likely to have seen, read or heard about the program and its messages in the media than parents in the remainder of the state (p < 0.001). Further, there was a significant increase in awareness of the program and each of its messages over time in HNE compared to no change over time in NSW (p < 0.001). Awareness was significantly higher (p < 0.05) in HNE compared to NSW after each specific campaign (except the vegetable one) and significantly higher awareness levels were sustained for each campaign until the end of the program. At the end of the program participants without a tertiary education were significantly more likely (p = 0.04) to be aware of the brand campaign (31%) than those with (20%) but there were no other statistically significant socio-demographic differences in awareness. CONCLUSIONS: The Good for Kids communication campaigns increased and maintained awareness of childhood obesity prevention messages. Moreover, messages were delivered equitably to diverse socio-demographic groups within the region.

Healthy food and beverages in senior community football club canteens in New South Wales, Australia.

ISSUE ADDRESSED: Little is known of the extent to which senior sports clubs support the consumption of healthy food and beverages. This study of senior community football clubs aimed to describe: i) the food and beverages available in club canteens; ii) the perceived acceptability of club representatives (e.g. club president or secretary) to selling healthy food and beverages in club canteens; iii) the perceived barriers of club representatives to providing healthy food and beverage options in their club canteen; iv) the associations between the availability of healthy options in canteens, perceived barriers to healthy food and drink availability, and club characteristics; and (v) the food and beverages usually purchased from canteens by club members. METHODS: The study involved 70 senior community football clubs (Australian Rules Football, Soccer, Rugby League and Rugby Union) across New South Wales, Australia. Club representatives and club members took part in cross-sectional telephone surveys. RESULTS: The most frequently available items at club canteens were regular soft drinks and potato chips or other salty snacks (available at 99% of clubs). Approximately two-thirds (66%) of club representatives agreed or strongly agreed that clubs should provide a greater variety of healthy food options. Perishability and lack of demand were the most frequently cited barriers to healthy food provision. Healthy food options were more available at AFL clubs compared with other football codes. Overall, 6% of club members reported purchasing a healthy food option. CONCLUSIONS: Senior community football clubs primarily stock and sell unhealthy food and beverage items. There is support within clubs for providing more healthy options; however, clubs face a number of barriers to the inclusion of healthy foods in club canteens.

Evaluating the consistency of gene sets used in the analysis of bacterial gene expression data.

BACKGROUND: Statistical analyses of whole genome expression data require functional information about genes in order to yield meaningful biological conclusions. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) are common sources of functionally grouped gene sets. For bacteria, the SEED and MicrobesOnline provide alternative, complementary sources of gene sets. To date, no comprehensive evaluation of the data obtained from these resources has been performed. RESULTS: We define a series of gene set consistency metrics directly related to the most common classes of statistical analyses for gene expression data, and then perform a comprehensive analysis of 3581 Affymetrix® gene expression arrays across 17 diverse bacteria. We find that gene sets obtained from GO and KEGG demonstrate lower consistency than those obtained from the SEED and MicrobesOnline, regardless of gene set size. CONCLUSIONS: Despite the widespread use of GO and KEGG gene sets in bacterial gene expression data analysis, the SEED and MicrobesOnline provide more consistent sets for a wide variety of statistical analyses. Increased use of the SEED and MicrobesOnline gene sets in the analysis of bacterial gene expression data may improve statistical power and utility of expression data.

Alcohol sponsorship of community football clubs: the current situation.

ISSUE ADDRESSED: There is accumulating evidence supporting a link between alcohol industry sponsorship and alcohol-related problems in both community and elite-level sports. Little is known, however, about the current status of such sponsorship, particularly of community sport. This study aimed to assess associations between alcohol industry sponsorship and different community football clubs in Australia. METHODS: The study involved 101 community football clubs across New South Wales, Australia. One representative from each club took part in a cross-sectional telephone survey designed to assess club (football code, number of players, socioeconomic and geographic descriptors) and alcohol industry sponsorship (money, equipment, free alcohol or discounted alcohol) characteristics. Chi-square analysis was used to test associations between club characteristics, and: i) any alcohol industry sponsorship; and ii) type of sponsorship. RESULTS: Eighty-eight per cent of clubs reported receiving sponsorship from the alcohol industry, and most clubs (82%) were sponsored by a licensed premises. There were no significant associations between club characteristics and source of alcohol industry sponsorship. However, small clubs were found to be significantly more likely to receive free or discounted alcohol sponsorship than larger clubs (p=0.05). CONCLUSIONS: This exploratory study suggests a significant presence of alcohol industry sponsorship among community football clubs in Australia.
