Background• Approximately 50 to 70 million Americans suffer from
insufficient sleep-related problems1-5
– Daytime sleepiness, fatigue, impaired cognitive function, weight gain, and mood disorders
• Frequent sleep insufficiency (FSI) affects 28.5% of the U.S. population2
• FSI is most commonly defined as having ≥14 days of insufficient sleep in the preceding 30 days
– Established in 1984– Annual, State-based, cross-sectional telephone survey– Collects information about behaviors associated with
preventable chronic diseases, injuries, and infectious diseases– Noninstitutionalized adults ≥18 with land-line telephones, from all 50 states, District of Columbia, Puerto Rico, and Virgin Islands– 2008: Added question to measure sleep insufficiency in all states, including Georgia
Covariates• Demographics: age, sex, race/ethnicity, and
• Independent variables: smoking, heavy drinking, leisure time physical activity (LTPA), and frequent mental distress (FMD)
Definitions
• Frequent sleep insufficiency (FSI): ≥14 days in response to: – “During the past 30 days, for about how many days have you felt you did not get enough rest or sleep?”
Definitions
• Frequent mental distress (FMD): ≥14 days in response to: – “Now thinking about your mental health, which
includes stress, depression, and problems with emotions, for how many days during the past 30 days was your mental health not good?”
• Smoking: “Yes” responses to:– “Current Smoker”
• Heavy Drinking:– Males that had ≥2 drinks per day; females that had ≥1
drinks per day
Definitions• No Leisure Time Physical Activity (LTPA):
“No” responses to:– “Adults that report doing physical activity or
exercise during the past 30 days other than their regular job”
• Body Mass Index (BMI) Status: – Normal: 18.5 ≤ BMI < 25 – Overweight: 25 ≤ BMI < 30 – Obese: BMI ≥ 30
Data Analyses
• Combined data from 2008, 2009, and 2010 Georgia BRFSS
• Bivariate associations between FSI and demographic and health risk factors
• Multivariable logistic regression analyses to derive Adjusted Odds Ratios (AOR) and 95% Confidence Intervals of factors associated with FSI
• SAS-callable SUDAAN (v.11.0.0) was used to conduct all analyses
Study Sample • Combined study sample: 17,400 GA adults• Study sample consisted of:
– Males (49%)– Females (51%)– NH White (63%)– NH Black (26%)– Hispanic (5%)– NH Other (6%)
• Overall prevalence of FSI among adults in GA was
28.5% (95% CI: 27.4 - 29.6)

Summary• Similar to other studies:
– the prevalence of FSI in Georgia was comparable to that for the US2
– individuals who were 25-34 years old, obese, physically inactive, smokers, and that had FMD were significantly more likely to report FSI3-6,8,12
– education level and race/ethnicity were not significantly associated with FSI5,6
• In contrast to other studies, heavy drinking and sex were not significantly associated to FSI; however, the direction of the associations were similar3-6,8-13
Public Health Implications• Interventions should be directed to promoting good mental
health, healthy weight management, smoking cessation, as well as to increasing physical activity
• Increasing awareness about negative effects of sleep loss is important to encourage sleep health and reduce FSI prevalence in Georgia
• Healthcare professionals need more training in order to effectively identify, diagnose, and treat sleep conditions among their patients
• More research is needed in order to determine specific risk factors associated to sleep insufficiency
Strengths
• FSI estimates among adults in Georgia
• Association of FSI with other health risk factors
• Population-based data from BRFSS allows results to be representative of the state of Georgia
Limitations
• Self-reported data
• Institutionalized individuals and those without landline phones not included– Results not generalizable to these populations
• Cross-sectional design does not allow determination of causality
• Only representative of Georgia
• Differences in FSI definitions in literature
