Background

• Sugar-sweetened beverage (SSB) consumption has been associated with weight gain and obesity, dyslipidemia, hyperglycemia, type 2 diabetes, and increased risk for cardiovascular (CV) events

• The association between SSB consumption and development of CV risk factors has not been extensively examined in large, prospective, multi-ethnic cohorts

Objective

• To quantify the association between SSB consumption and risk for developing individual CV risk factors in men and women in the Multi-Ethnic Study of Atherosclerosis (MESA)

MESA Study Description6,814 participants recruited in 2000-2002

Field Centers:- Baltimore - New York

- Chicago - St. Paul

- Los Angeles - Winston-Salem

• 45-84 years, free of clinical cardiovascular disease

• 57% women • 38% Non-Hispanic White, 28% African-American,

22% Hispanic, 12% Chinese American

Assessment of SSB Intake

• Food Frequency Questionnaire (FFQ) was used to measure SSB consumption at the first exam (2000-2002)

• The FFQ specifically asked about consumption of “regular soft drinks, soda, sweetened mineral water (not diet), and nonalcoholic beer”

• SSB intake was categorized into the following groups: 0-<1, 1-<2, and 2+ servings per day

CV Risk Factors Definitions (1)

• Weight Gain: Weight on any follow-up exam or average of all exam weight measurements >3% higher than baseline

• Increased Waist Circumference (WC): WC from any follow-up exam or average of all exam WC measurements >3% higher than baseline

• High Triglycerides: HDL >40 mg/dL (men), > 50mg/dL (women), LDL <160mg/dL, and triglycerides >150mg/dL

• Low HDL cholesterol: HDL <40mg/dL (men), <50 mg/dL (women), LDL <160mg/dL, and triglycerides <150mg/dL

• Impaired Fasting Glucose: Fasting plasma glucose 100-125 mg/dL

• Type 2 Diabetes (T2D): Fasting glucose ≥126 mg/dL, medication use for T2D or self-reported T2D

CV Risk Factors Definitions (2)

Selection of Study Participants for the Current Study

8

6,814 MESA participants ages 45-84 and free of clinical CVD at first exam

General Analysis Sample (n=4,166)

Lipid Analyses (n=1,614)

IGT Analyses (n=3,437)

Excluded Participants

No follow up exams (n=761)

Type 2 diabetes at baseline(n=773)

BMI <18.5 kg/m2 at baseline (n=37)

Missing covariates of interest (n=1,077)

Additional Exclusions

Lipid Medication Use (n=2,552)

Impaired fasting glucose at baseline (n=729)

Statistical Analyses• Cox proportional hazards regression used

estimate hazard ratios

• All risk estimates adjusted for:

• Age

• Sex

• Race/ethnicity

• Study center

• Educational attainment

• Intentional exercise

• Smoking status

• Dietary intake (i.e., total energy, fiber, saturated fat, cholesterol, fruits and vegetables, sodium)

• Family history of T2D (for T2D

incidence)

• Time-varying BMI and WC

Summary• Women who consumed 2+ SSBs per day

exhibited higher risk for developing:

– high triglycerides

– impaired glucose tolerance

– increased waist circumference

compared to women who consumed <1 SSB per day

• These associations remained even after accounting for baseline and time varying BMI and WC

18

Strengths and LimitationsStrengths• The MESA study is a large, population-based

cohort designed to examine the development of

CVD risk factorsLimitations• Food frequency item used likely to not have

captured all types of SSBs consumed

American Beverage Association

"This type of study cannot show that drinking sugar-sweetened beverages

causes increased risk for cardiovascular disease. It simply looks at associations

between the two, which could be the result of numerous other confounding factors.”

Conclusions

• The influence of SSBs consumption on cardiovascular risk is complex and may not be the same between middle- and older-aged men and women

• Women exhibit lower energy requirements compared to men and may therefore experience higher CV risk when a greater proportion of calories is consumed in the form of SSBs
