The aims of our study were to describe these intervention strategies implemented in PRIR from 2007 to 2012 on increasing the seat belt usage rates and reducing deaths from MVCs, to investigate the effectiveness of the intervention strategies, and to determine if changes are necessary to improve these intervention strategies for MVC injury prevention among Native Americans.
Existing data on MVC fatalities and seat belt usage rates from federal, state, and tribal sources were collected for the years 2002-2012 for Native Americans on PRIR and all races in South Dakota and nationally.
MVC fatality data for Shannon, Jackson, and Bennett counties were collected from the NHTSA FARS database for MVC fatalities that occurred within PRIR boundaries between 2002 and 2011 regardless of race.
Data on seat belt usage rate in PRIR from 2007 to 2012 were obtained from a series of surveys conducted in the reservation by the OST DPS with the assistance of the IHS Pine Ridge OEH.
A local highway safety coalition named Sacred Cargo Coalition was created in PRIR in 2007 to take the responsibility of gathering information on the MVC injury issues facing the reservation and of selecting, prioritizing, and implementing intervention strategies in the community by improving seat belt use to reduce MVC fatalities.
The intervention strategies would be considered effective if the goals set by the Sacred Cargo Coalition were achieved as follows: 1) seat belt usage rates in PRIR increase by 10 percentage points each year from 2007 to 2012 (50 points overall); 2) MVC fatalities decrease by 5% from 2007 to 2011 (six overall fewer deaths during the intervention).
Compare the PRIR with Puerto Rico's rate of participation in the world total exports denominated PRRP (Puerto Rico's rate of participation in total world exports for a given year).
If the PRIR is higher that the PRRP, the industry is considered competitive at the international level for that year and is included in the cluster chart.
Although the number of competitive industries measured by its PRIR was lower in 2001 and 2002, Puerto Rico's rate of participation in total world exports (PRRP) was higher for those years.
Below the office machinery manufacturing, which appeared in the cluster charts with a significant PRIR in 2003, are included firms that manufacture supplies like toner for printers, electronic components, and certain devices for printers and books reproduction in digital media.
Although its PRIR does not surpass the PRRP by one, this is an emergent industry on the Island.
