About this study

Official title: Effects of Daily Inclusion of Eggs in a Heart-Healthful Dietary Pattern on Cardio-Metabolic Risk Factors and Diet Quality in Hyperlipidemic Adults

This randomized, cross-over design, controlled trial will assess the effects of 8 weeks of daily inclusion of 2 whole eggs in the Dietary Approaches to Stop Hypertension (DASH) eating plan, compared with their exclusion, on cardio-metabolic risk markers and diet quality in hyperlipidemic adults.

Read the detailed description

This randomized, cross-over design, controlled trial will assess the effects of 8 weeks of daily inclusion of 2 whole eggs in the Dietary Approaches to Stop Hypertension (DASH) eating plan, compared with their exclusion, on cardio-metabolic risk markers, and diet quality in hyperlipidemic adults. Participants will be randomized to receive 1 of 2 treatment sequence permutations (i.e., DASH eating plan with eggs and DASH eating plan without eggs), with an 8-week washout period between treatment assignments. After randomization, participants will undergo a 4-week run-in period of a DASH eating plan without egg products before initiating the first of 2 treatment phases in their randomly-assigned sequence permutation.

Specific Aims

  1. To assess the effects of the inclusion of 2 whole eggs/day for 8 weeks in a DASH eating plan, as compared with their exclusion, on endothelial function measured as flow-mediated dilatation and on LDL cholesterol in hyperlipidemic adults.
  2. To determine the effects of the inclusion of 2 whole eggs/day in the context of a DASH eating plan, as compared with their exclusion, on cardio-metabolic risk factors and diet quality in adults with hyperlipidemia over a period of 8 weeks.

  12. Satiety, measured on a Visual Analogue Scale (VAS)

    At the end of each 8-week treatment period, following an 8-hour fast, subjective satiety will be assessed using an ordinal Visual Analogue Scale (VAS) self-administered to participants by the study coordinator at a predetermined time relative to the consumption of a meal or snack. Participants will be asked to complete the VAS at 0 minute, and at 30-minute intervals up to 120 minutes after consuming the meal or snack. The VAS has 5 questions that ask participants to rate the strength of specific sensations that they are feeling (i.e., hunger, thirst, amount of food that they could eat "right now", nausea, and fullness) by placing a vertical mark on a corresponding scale in response to each question. A composite score from each of the 5 scales will then be used by the study coordinator to estimate a total value for satiety.

    Measured: At the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  13. Body weight, kilograms

    Body weight will be measured by a clinical research specialist to the nearest 0.5 kilogram using a balance-type medical scale. Participants will be measured in the morning (fasting), unclothed except for undergarments.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  14. Body mass index (BMI) (weight in kg/height in meters squared)

    The Tanita SC-240 Body Composition Analyzer (Tokyo, Japan) will be used by a clinical research specialist in the PRC lab by asking the participant to stand on the scale. Weight will be measured using the SC-240 Analyzer. Height will be measured on a balance scale and will be manually entered into the Tanita Analyzer, which will be combined with the weight measure to calculate BMI.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  15. Body fat, %

    The Tanita SC-240 Body Composition Analyzer (Tokyo, Japan) will be used by a clinical research specialist in the PRC lab by asking the participant to stand on the scale. The SC-240 Analyzer uses bioelectrical impedance analysis to calculate body fat%.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  16. Body water, %

    The Tanita SC-240 Body Composition Analyzer (Tokyo, Japan) will be used by a clinical research specialist in the PRC lab by asking the participant to stand on the scale. The SC-240 Analyzer uses bioelectrical impedance analysis to calculate total body water%.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  17. Visceral fat rating

    The Tanita SC-240 Body Composition Analyzer (Tokyo, Japan) will be used by a clinical research specialist in the PRC lab by asking the participant to stand on the scale. The SC-240 Analyzer uses bioelectrical impedance analysis to calculate a rating for visceral fat located deep in the core abdominal area. A rating in the range of 1 to 12 indicates a healthy level of visceral fat. A rating in the range of 13 to 59 indicates an excess level of visceral fat.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  18. Waist circumference, cm

    Waist circumference will be measured using the U.S. government standard protocol. A clinical research specialist will ask the participant to stand and will place a measurement tape around the participant's waist, at the level of the belly button. The clinical research specialist will ensure that the tape is horizontal around the participant's waist, and will then keep the tape snug around the participant's waist while not compressing the skin, and will measure her/his waist just after exhaling.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  19. Diet quality, using the Healthy Eating Index 2015 (HEI-2015)

    To track any variation in dietary pattern over the course of the study, participants will be asked to provide information on the foods and beverages consumed during a 3-day period (i.e., 2 weekdays and 1 weekend day). For each 3-day period, participants will complete three 24-hour recalls using a web-based Automated Self-Administered 24-Hour Recall (ASA24), a dietary assessment software program that will guide them through the process of completing the recall data; these data (which will be captured and stored within the ASA24 program's database) will be reviewed by a member of the study team. Diet quality based on the information provided will be assessed using the Healthy Eating Index 2015 (HEI-2015), which will generate a scale ranging from 1-100, with a higher value indicating a relatively better overall quality of the diet.

    Measured: Change from baseline at the end of each 8-week treatment period: DASH eating plan with eggs; DASH eating plan without eggs

  20. Physical activity level (PA), kilocalories

    Participants' PA levels will be assessed by the study coordinator using the Seven-Day Physical Activity Recall questionnaire (PAR) in the course of a semi-structured interview. The PAR is a valid and reliable tool to estimate the total amount of kilocalories expended on physical activity in adults during the past week. It asks participants to report the amount of time spent in the past week on household and yard-work activities, occupational activity, transport, leisure time physical activity and sedentary behavior. The type, duration in hours, and level of intensity of reported physical activities are then used to estimate the total amount of kilocalories expended on PA during the past week.
