“…Some researchers also collect GIS data for their own specific study objectives. For example, common ways to collect such data include using portable Global Positioning System devices and tablet personal computer technology to collect spatial data and using interviews or questionnaires to collect both spatial and non‐spatial data . These types of data could present more up‐to‐date and accurate information, but fall short of comparability with other local collections and are also difficult to be collected on a large scale because of constraints of time and labour.…”

Applications of geographic information systems (GIS) data and methods in obesity‐related research

Geographic information systems (GIS) data/methods offer good promise for public health programs including obesity-related research. This study systematically examined their applications and identified gaps and limitations in current obesity-related research. A systematic search of PubMed for studies published before 20 May 2016, utilizing synonyms for GIS in combination with synonyms for obesity as search terms, identified 121 studies that met our inclusion criteria. We found primary applications of GIS data/methods in obesity-related research included (i) visualization of spatial distribution of obesity and obesity-related phenomena, and basic obesogenic environmental features, and (ii) construction of advanced obesogenic environmental indicators. We found high spatial heterogeneity in obesity prevalence/risk and obesogenic environmental factors. Also, study design and characteristics varied considerably across studies because of lack of established guidance and protocols in the field, which may also have contributed to the mixed findings about environmental impacts on obesity. Existing findings regarding built environment are more robust than those regarding food environment. Applications of GIS data/methods in obesity research are still limited, and related research faces many challenges. More and better GIS data and more friendly analysis methods are needed to expand future GIS applications in obesity-related research.

“…The Johns Hopkins Center for a Livable Future GIS maps in addition to ground truthing techniques aided in identifying corner stores for recruitment (Coakley et al, 2014; Haering & Franco, 2010). Recruited stores were those that agreed to participate and met the following criteria: (1) located within a 1-mile radius of a recreation center, (2) reported being frequently visited by the priority population (10–14-yearold children), (3) independently owned and operated (Buczynski et al, 2015; Gittelsohn et al, 2014).…”

Higher rates of obesity and obesity-related chronic disease are prevalent in communities where there is limited access to affordable, healthy food. The B’More Healthy Communities for Kids (BHCK) trial worked at multiple levels of the food environment including food wholesalers and corner stores to improve the surrounding community’s access to healthy food. The objective of this article is to describe the development and implementation of BHCK’s corner store and wholesaler interventions through formal process evaluation. Researchers evaluated each level of the intervention to assess reach, dose delivered, and fidelity. Corner store and wholesaler reach, dose delivered, and fidelity were measured by number of interactions, promotional materials distributed, and maintenance of study materials, respectively. Overall, the corner store implementation showed moderate reach, dose delivered, and high fidelity. The wholesaler intervention was implemented with high reach, dose, and fidelity. The program held 355 corner store interactive sessions and had 9,347 community member interactions, 21% of which were with children between the ages of 10 and 14 years. There was a 15% increase in corner store promoted food stocking during Wave 1 and a 17% increase during Wave 2. These findings demonstrate a successfully implemented food retailer intervention in a low-income urban setting.

“…BHCK used maps developed with the Johns Hopkins Center for a Livable Future Geographic Information System in addition to ground truthing techniques to recruit carryouts [15]. Carryouts were eligible for recruitment if they were within an Implementation of a carryout intervention intervention or control zone and were frequented by youth (as determined by interviews with carryout owners).…”

Youth obesity is a major public health problem in the United States, especially among urban-based, minority youth. The B'More Healthy Communities for Kids (BHCK) trial worked at multiple levels of the food environment, including carryouts, to increase access to and demand for healthy, affordable foods. The objective of this article is to describe the development and implementation of BHCK's carryout intervention. Process evaluation was conducted to assess intervention reach (number of interactions with youth and adults either in person or on social media), dose delivered (number of food samples and promotional materials distributed, social media posts and meetings with owners) and fidelity (availability of promoted items). Overall, the carryout intervention showed moderate to optimal reach, moderate to optimal dose delivered and moderate to optimal fidelity. These findings demonstrate a successfully implemented carryout intervention in a low-income urban setting. Lessons learned about new methods for engaging the community and increasing demand for healthy food can be used to inform future studies and programs to improve the food environment.
