About this study

Official title: The Impact of Dietary Habits and Nutrition Intervention on Metabolic Syndrome Parameters in Hospitalized Individuals With the Diagnosis of Schizophrenia

Metabolic syndrome is a term used to describe a complex clinical condition that includes abdominal obesity, increased level of serum triglycerides, elevated blood pressure, decreased level of high-density lipoprotein cholesterol, and high fasting glucose level. Metabolic syndrome represents one of the major risk factors for the development of cardiovascular diseases and type 2 diabetes mellitus. According to the results of numerous previously conducted studies, the prevalence of metabolic syndrome among the individuals with schizophrenia is higher than in the general population.

The reasons for the higher prevalence of metabolic syndrome among the individuals with schizophrenia are not yet fully clarified. Nevertheless, unhealthy dietary habits are considered to be one of the main factors that could have an impact on metabolic syndrome development. According to the results of published studies, individuals with schizophrenia have poorer dietary habits when compared to people without mental disorders.

Although there are numerous previously published studies focused on the impact of nutritional interventions on metabolic syndrome in individuals with schizophrenia, there is still no consensus on what would be the most appropriate nutrition therapy for the treatment of metabolic syndrome in this specific population group. Furthermore, the vast majority of the published studies have been conducted on outpatients, with only a small number of them being carried out on hospitalized individuals with a diagnosis of schizophrenia.

Dietary Approaches to Stop Hypertension (DASH) diet is primarily intended to those individuals with elevated blood pressure, but according to some authors, it could have beneficial effects in the treatment of the metabolic syndrome as well. DASH diet represents a healthy way of eating with a special emphasis on low-fat dairy products, fruits, vegetables and whole grains, together with an overall reduction in sodium intake.

Therefore, the present study aims to determine the impact of dietary habits and nutrition intervention on metabolic syndrome parameters in hospitalized individuals with the diagnosis of schizophrenia.

The investigators hypothesize that the intervention will result in the improvement in metabolic syndrome parameters, the amelioration in dietary habits, and the reduction in body weight.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dietary Approaches to Stop HypertensionOther

    Also called DASH diet

    The DASH diet will have a reduced caloric intake by 400 kcal/day, when compared to the standard hospital diet. The DASH diet will be planned according to the following: total daily energy intake 1,900 kcal; total daily fat intake 27%; daily intake of saturated fatty acids 6%; total daily protein intake 18%; total daily carbohydrates intake 55%; cholesterol 150 mg/day; sodium 2,300 mg/day; potassium 4,700 mg/day; calcium 1,250 mg/day; magnesium 500 mg/day; and fiber 30 g/day.

  • Nutrition education programOther

    The nutrition education program will consist of four lectures intended to improve the overall participants' dietary habits. The lectures will be interactive and will be organized in smaller groups (up to 10 participants) covering the following themes: My Plate dietary guidelines; Principles of a balanced diet; Reading and understanding food nutrition labels; Dietary recommendations for elevated blood pressure, dyslipidemia, and diabetes mellitus.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in waist circumference

    Waist circumference measuring (in cm) will be performed prior to and immediately after the intervention using a non-strechable measuring tape.

    Measured: Baseline and after three months

  2. Change in blood pressure

    The assessment of blood pressure (in mmHg) will be performed prior to and immediately after the intervention using an aneroid blood pressure gauge.

    Measured: Baseline and after three months

  3. Change in high-density lipoprotein cholesterol

    The blood serum concentration of high-density lipoprotein cholesterol (in mmol/L) will be determined prior to and immediately after the intervention. Blood samples will be collected after the overnight fast and the analysis will be performed on the Cobas c 111 analyzer.

    Measured: Baseline and after three months

  4. Change in serum triglycerides

    The concentration of serum triglycerides (in mmol/L) will be determined prior to and immediately after the intervention. Blood samples will be collected after the overnight fast and the analysis will be performed on the Cobas c 111 analyzer.

    Measured: Baseline and after three months

  5. Change in fasting blood glucose

    The blood serum concentration of glucose (in mmol/L) will be determined prior to and immediately after the intervention. Blood samples will be collected after the overnight fast and the analysis will be performed on the Cobas c 111 analyzer.

    Measured: Baseline and after three months

Secondary outcomes (10)
  1. Change in dietary habits

    Dietary habits will be assessed using the nutrition section of Dlugosch \& Krieger's General Health Behavior Questionnaire both prior to and immediately after the intervention.

    Measured: Baseline and after three months

  2. Change in individual food purchase habits

    Individual food purchase diaries, collected at the beginning and at the end of the intervention period, will be used for the evaluation of the changes in individual food purchase habits.

    Measured: Baseline and after three months

  3. Dietary intake during the intervention

    Dietary intake during the intervention will be assessed using three non-consecutive 24-hour dietary recalls (two weekdays and one weekend day).

    Measured: 3 months

  4. Change in participants' mental condition

    The global severity of the psychotic illness and severity of specific syndromes within psychotic illness will be evaluated prior to and immediately after the intervention using Signs and Symptoms of Psychotic Illness (SSPI) scale. The scale consists of 20 items (signs and symptoms of psychotic illness). For each item (subscale) a score in the range 0 - 4 is assigned: 0 - no psychopatology; 1 - a deviation questionably pathological; 2 - mild pathological deviation; 3 - pathology of moderate severity; 4 - severe psychopathology. Subscales are summed to determine a global severity of psychotic illness. The highest total score is 80.

    Measured: Baseline and after three months

  5. Change in body weight

    Body weight (in kg) will be measured prior to and immediately after the intervention using a digital medical scale witl stadiometer.

    Measured: Baseline and after three months

  6. Change in body mass index

    The measured values of body height and weight will be used for the calculation of body mass index (in kg/m^2).

    Measured: Baseline and after three months

  7. Change in waist-to-hip ratio

    The waist-to-hip ratio will be calculated from the measured values of waist and hip circumferences: waist circumference (cm) / hip circumference (cm).

    Measured: Baseline and after three months

  8. Change in body fat percentage

    Determination of body fat percentage will be performed using OMRON BF500 analyzer.

    Measured: Baseline and after three months

  9. Change in total cholesterol

    The concentration of total cholesterol (in mmol/L) will be determined prior to and immediately after the intervention. Blood samples will be collected after the overnight fast and the analysis will be performed on the Cobas c 111 analyzer.

    Measured: Baseline and after three months

  10. Change in low-density lipoprotein cholesterol

    The concentration of low-density lipoprotein cholesterol (in mmol/L) will be determined prior to and immediately after the intervention. Blood samples will be collected after the overnight fast and the analysis will be performed on the Cobas c 111 analyzer.

    Measured: Baseline and after three months
