ABSTRACT

Background:

Hospitalization may seriously affect patients’ nutritional status and may ‎occasionally be accompanied by malnutrition development or aggravation. Food intake is ‎often altered during hospitalization, which is tightly connected to malnutrition. On the other ‎hand, a huge amount of plate food wasted by patients, in addition to its health consequences, ‎has enormous economic and environmental expenses for governments and societies.

Objective:

This ‎investigation aims firstly to assess the nutritional status of the patients hospitalized in general ‎wards and secondly to evaluate the quantity and financial burden of patients’ food waste ‎along with its possible nutritional outcomes.‎

Methods:

A mixed-method study is performed in three general hospitals in Tehran. Adult ‎inpatients with eligibility criteria are recruited to the study from medical and surgical ‎wards. Anthropometric and demographic data are collected and energy and protein intakes ‎are extracted from a 24-hour food recall. Plate food wastes of eligible patients are weighed ‎in breakfast, lunch, and snacks during one day. Then, the economic cost of food waste is ‎calculated for each meal, patient, and ward. Nutritional status is determined through the ‎following methods: 1. Subjective criteria (Mini Nutritional Assessment and Subjective ‎Global Assessment tools) for malnutrition; 2. Measuring serum albumin, pre-albumin and ‎total protein for protein status; 3. Measuring serum retinol and 25-hydroxycalciferol assay ‎to assess certain micronutrient status (vitamins A and D); and 4. Examination of serum β-‎carotene, total antioxidant capacity, malondialdehyde, and highly sensitive C-reactive ‎protein to determine oxidative stress and inflammatory status. Also, a qualitative study is ‎conducted to evaluate the possible reasons for wasting food in these hospitals.‎

Results:

-----

Conclusions:

This study will provide appropriate data regarding the health and economic burden ‎of food waste in studied hospitals. These data are especially useful to healthcare authorities ‎and policymakers for planning efficient solutions to decrease food waste and to improve ‎patients' nutritional status. ‎
