Large-for-Gestational Age (LGA)

Singleton live births with a birth weight more than the 90th percentile of birth weights of the same sex and the same gestational, expressed as a percentage of live singleton births with gestational ages from 22 to 43 weeks. The current Canadian reference percentile tables can be found at http://www.phac-aspc.gc.ca/rhs-ssg/bwga-pnag/index-eng.php.

Leisure Time Activity Level

This variable is a measure of the average daily energy expended during leisure time activities by the respondent in the past three months.

Energy Expenditure (EE) is calculated using the frequency and duration per session of the physical activity as well as the MET value of the activity. The MET is a value of metabolic energy cost expressed as a multiple of the resting metabolic rate.

(CCHS Derived Variable document 2009/10)

Life Expectancy

The average length of time that an individual will live if subjected to the mortality experience for the specified population and time period.

Limitations of Survey Data

Self-reported survey data is valuable because it assesses behaviours in the population, data not usually collected elsewhere, but it is not the most reliable source of health data.  People are not always aware of or truthful about their health behaviours, their height and their weight when asked in a survey.

Low Birth Weight Rate

Number of live births weighing less than 2500 grams (5 lbs, 8 oz) at birth per 100 live births.

Low Income Cut-Off

Low income cut‐offs (LICOs) are income thresholds, determined by analyzing trends in family spending. Values below the low income cut-off indicate that individuals or families may be devoting a larger share of income than the average family on the necessities of food, shelter and clothing. The LICO is reported based on after-tax income.

Low Risk Drinking Guidelines

Canada's Low Risk Drinking Guidelines indicate no more than 2 standard drinks on any one day for women and no more than 3 standard drinks on any one day for men with a maximum of 10 and 15 standard drinks a week for women and men, respectively. A couple of days with no alcohol drinking should be taken each week. (http://www.ccsa.ca/Eng/topics/alcohol/drinking-guidelines/Pages/default.aspx)
