Dietary Acid Load and Oral Health Quality in Adolescents

This study investigates the link between dietary acid load and oral health-related quality of life in 374 high school students (226 females, 148 males). Participants completed a demographic questionnaire, the OHIP-14 scale, and provided 24-hour dietary recalls. Dietary acid load was assessed using PRAL and NEAP calculations. Data analysis was performed with SPSS 24 to explore the impact of diet composition on adolescents' oral health.

About this study

Introduction: Oral health plays a crucial role in the psychological and physical development of children and adolescents. The composition of the diet consumed significantly affects oral health.

Objective: This study aimed to examine the relationship between dietary acid load and oral health-related quality of life in adolescents.

Method: A total of 374 high school students (226 females, 148 males) participated in the study. Adolescents completed a demographic questionnaire and the Oral Health Impact Profile-14 (OHIP-14) scale, and 24-hour retrospective food consumption records were collected. Dietary acid load was assessed by calculating potential renal acid load (PRAL) and net endogenous acid production (NEAP) based on macronutrient and micronutrient intake from food records. Data analysis was conducted using the SPSS 24 software package.

Treatment and study plan

Primary outcomes

  1. Oral Health Impact Profile-14 Score

    Time frame: Baseline

    This scale was used to assess the quality of life related to oral health and how oral health affects overall quality of life and general health.

    The scale consists of 14 items with 5-point Likert-type questions (each option ranging from 0 to 4 points) and was designed using a five-choice scaling method. It was concluded that as the total score increased, the severity of the problem also increased, leading to a decrease in quality of life.

  2. Calculation of Dietary Acid Load

    Time frame: Baseline

    Dietary acid load (DAL), potential renal acid load (PRAL), and net endogenous acid production (NEAP) were calculated based on the 24 hours food consumption record The formula for PRAL is as follows:

    PRAL (mEq/day) = 0.4888 x protein (g/day) +0.0366 x phosphorus (mg/day)-0.0205 x potassium (mg/day) - 0.0125 x calcium (mg/day) - 0.0263 x magnesium (mg/day) NEAP (mEq/day) = [54.5 x protein (g/day) / potassium (mEq/day)] - 10.2 High and positive PRAL and NEAP values indicate a high dietary acid load.

Secondary outcomes

  1. Sociodemographic characteristics

    Time frame: Baseline

    Sociodemographic characteristics will be assessed using a structured questionnaire developed by the researchers. The questionnaire will include items measuring age, gender, education level, and income status. The results will be presented as numbers and percentages for each characteristic.

  2. Body Mass Index (BMI)

    Time frame: Baseline

    Kilograms per square meter (kg/m2)

  3. Height

    Time frame: Baseline

    Height in cm

  4. Body weight

    Time frame: Baseline

    Body weight in kg
