In this study, conducted in Nova Scotia, Canada, we surveyed people at farmers' markets, agricultural fairs, and other agricultural events to investigate the views of people who would likely be trying to incorporate local food into their everyday shopping habits. Survey respondents (N = 2,316) indicated strong positive beliefs, attitudes, and propensity toward buying local food. At the same time, however, they reported difficulty identifying whether food was local as well as a lack of opportunities to buy local food. The findings build upon the growing body of research surrounding the "buy local" movement in North America by providing insight into why people want to buy local and potential barriers that prevent stronger markets for local food products.
Successful recruitment and retention for population-based longitudinal studies requires understanding facilitators and barriers to participation. This study explored Canadians' views regarding one such study, the proposed Canadian Longitudinal Study on Aging (CLSA). Focus groups of participants > or =40 years of age were held in six proposed CLSA data collection sites (Halifax, Montreal, Hamilton, Winnipeg, Calgary, and Vancouver) to discuss participating in a long-term study of healthy aging. There was fundamental support for longitudinal research on health and aging. Altruism was a key motivation to participation, and universities were viewed as credible parties to conduct such studies. Participants had few worries about providing biological samples but expressed concern about potential misuse of genetic materials, commercialization of participant data, and privacy issues. These findings have already informed current, and will inform future, work on the CLSA, and will also provide useful information to researchers who undertake other population-based longitudinal studies.
RÉSUMÉOn a examiné la prévalence, les facteurs de risque et les troubles médicaux associés aux déficiences de la vue et de l'ouïe chez les adultes canadiens de 55 ans et plus. On a établi un échantillonnage aléatoire à partir des recensements canadiens de 1986 et 1991 et on a demandé aux citoyens qui en faisaient partie de remplir le Sondage sur la santé et les limitations d'activité (ESLA) de 1986 et 1991. On a constaté que les aîné(e)s de 65 ans et plus présentaient plus de déficiences sensorielles que ceux de 55 à 64 ans. Les hommes signalaient plus de difficultés de l'ouîe que les femmes tandis que les femmes présentaient plus de difficultés de la vue que les hommes. On a constaté que l'incidence des difficultés sensorielles semblait augmenter avec l'âge et avec la diminution de revenu total de la maisonnée. Ce sont les cataractes et la surdité qui ont été le plus souvent mentionnées comme cause de restriction des activités de la vie quotidienne dans les deux groupes d'âge. Les difficultés sensorielles sont fréquentes chez les aîné(e)s. Les initiatives de santé publique devraient se pencher sur les difficultés de la vue et de l'ouïe, particulièrement chez les aîné(e)s, les femmes et les gens à faible revenu.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
