Final Flashcards
why do people in older cities weigh less than people who live in newer ones
people in older cities tent to walk more than people in newer cities. Urban Planning. When older cities were build they had no cars so they did not build the cities for cars so in some areas you can’t drive
deprivation amplification
the relationship between the opportunities a community has to offer and the income and education of its residents
how do socioeconomic groups dictate the environment
clusters of money dictate what the environment will be shaped like
relationship between setting and groups
the setting dictates what the group is and the group dictates what the setting is
MacIntyre’s 5 Features of (Un)Healthy Neighbourhoods
1) Physical Features of the Environment - air, water, climate
2) Availability - of healthy environments at home, work, & play (settings approach)
3) Public or Private Services: to support daily living (neo-materialistic)
4) Socio-Cultural Features: the political, economic, ethnic & religious norms, culture & activities
5) The Reputation of an Area: as perceived by residents, planners & investors
Spatial Segregation
Those living in lower income neighbourhoods are more likely to develop poorer health/disease than those in well-off neighbourhoods
Poorest areas found to have: 3x more places to consume alcohol; 4x fewer supermarkets and fresh food sources; 2.5x higher density of fast food outlets
The Built Environment
refers to all human-made surroundings - the spaces where we live, work, and play & includes tangible structures such as buildings, streets, parks, businesses, schools, road systems, transportation networks, & other infastructure
Built Environment Considers
- Aesthetics
- Street design (walkability, connectivity)
- Availability of Services
- Density and live-abiliy
how does the built environment influence our health?
- options for physical activity
- access to healthy food choices
- feelings of safety
- sense of pride and belonging (community)
obesogenic environments
concept that ‘place’ affects eating, exercising, & body weight –> encourage the consumption of fast foods and discourage physical activity
example of an obesogenic environment
car accessible fast food outlets
moving to more-socioeconomically deprived neighbourhood is associated with
weight gain
High levels of greenery
residents are 3x more likely to be physically active & the likelihood of being obese was 40% less
high levels of incivility (litter, graffiti, garbage)
likelihood of PA is 50% less, likelihood of being overweight or obese is about 50% higher (the environment does not want make you feel like you want to be part of the community)
what is the best set up for a city that enables people to get places by foot
linear setup, more compact, fewer lanes (grid-like areas)
–> correlated with reduced risks of obesity, diabetes, high blood pressure, and heart disease
Sprawl
low density, separated land uses, automobile dominance & minimal public space
(expansion of human populations away from urban areas into low-density, monofunctional, and usually car dependant communities)
Ideal ‘land use mix’
retail, office, residential, open green space & schools should be integrated rather than separated. Best mix is where habitual activities (home, school and work) are co-located with less habitual activities (entertainment, retail)
Disadvantages of sprawling communities
people in these communities walk less in their leisure time, weigh more, and have higher blood pressure as compared to those who live in more ‘compact communities’
relationship between land use mix and obesity
inverse relationship
Connectivity
the ease of travel between two points, or the degree to which streets or areas are interconnected
- –> development of ‘cul de sacs’ versus grids
- -> sidewalk characteristics
key sidewalk characteristics
lighting, benches, greenery, washroom access
why is good public transit important
if you can have good public transit it helps people who don’t have cars access healthy public spots
Social mobility
giving people access to public transit and therefore access to social services
why don’t bike sharing programs work that well
people who want to ride bikes will, and people who don’t want to wont.
not the best method for increasing PA and lowering CO2 emissions
Active transportation
any form of human-powered transportation (walking, cycling)
active travel is declining
smart growth principles
- preserve open green space
- compact building design
- mix land uses
- range of housing options
- transportation options
- walkable neighbourhoods
- distinctive, attractive communities
- stakeholder collaboration and partnerships
why do lots of many parents not let their kid walk to school
parents reported that they would let their child walk or bike to school if: there are safer routes to school, and if their child is not alone
Direct influences to healthy eating
- food system (agriculture, trade, retail, ads)
- daily living conditions (accessibility, norms, policies, income, education, cultural values)
food insecurity & security
the inability to acquire or consume in an adequate diet quality or sufficient quantity of food in socially acceptable ways, or the uncertainty that one will be able to do so.
food insecurity and security stats
7% of Canadians can not afford balanced meals. 11.5% either did not have enough food or not enough of the right kind of food for a healthy diet.
Food Deserts
- the influence of one’s neighbourhood (SES and physical/built environment) on food choices: limited or no access to affordable fresh foods, produce
- high availability and affordability of fast food, convenience, tobacco and alcohol outlet products
Food deserts result from
- unsafe neighbourhoods and lack of public transit/walking routes to travel to supermarkets
- non-chain stores, food theft, sale of brand products & smaller packaging drives up food costs
- sense of loyalty to small businesses in the community ??
food environments
influence ‘choice’ through price, marketing and built environment
how do companies get children to buy bad food
cereal boxes (eye contact, height) advertising (63% of advertisements were for foods high in fat or sugar, 14% were for fast food)
drivers of larger portion size
- larger packages in grocery stores
- larger servings in restaurants
- larger dishware in homes –> increase in the appropriate perceived portion size –> increase in the amount of food eaten during a single eating occasion
tell me about price and sales
labelling vending-machine snacks as low in fat did little to increase sales but lowering the price really increased sales
3 factors that make someone eat healthily
- Convenient: a restaurant, grocery store, school cafeteria, or spouse made foods like fruits & vegetables easy to reach
- Attractive: enticingly displayed
- Normalized: appears to be an obvious choice
Issues with menu labelling
may be complicated, back of the package, hard to read
Research tells us that (food labelling)
- Short labels on front of package - shoppers had better beliefs about the product when reading a short claim on a front-label than if reading a long claim
- Simple images, even emojis, can communicate
- on the spot information about food - (e.g. calories on menus)
- Fat taxes - Danish experiment introduced the first tax on saturated fat in 2011. Repealed 15 months later
- Policies? - e.g. removal of trans-fats, sugary drinks sales policy, vending machine and food selections in public spaces
how to address inequity in healthy eating (3 things)
- Socio-political and cultural factors
- daily living
- individual
socio-political and cultural factors of healthy eating:
- nutrition specific policies
- economic instruments
- food labelling
- food reformulations
- food relief and aid focused on healthy options
- social norms (celebrity, ads, social marketing)
