SURVEY KONSUMSI PANGAN PERTEMUAN 3 DUDUNG ANGKASA PROGRAM STUDI ILMU GIZI-FIKES

VISI DAN MISI UNIVERSITAS ESA UNGGUL

KEMAMPUAN AKHIR YANG DIHARAPKAN Mahasiswa dapat menjelaskan prinsip pemilihan metode sesuai dengan tingkat tujuan

METHODS AND OBJECTIVES (1/2) Level 1: mean intake of a group § Measure food intake of subject for one day only § Ensure all days were covered in final sample Level 2: proportion ‘at risk’ to inadequate intakes § Measure food intake for at least two days on sub-sample (30 -40 subject) § Non-consecutive days should be used at two repeat. If not, three consecutive days are needed

EXAMPLE OF OBJECTIVE FOR LEVEL 1 AND 2 Level 1 § To describe usual mean nutrient intake for a group with certain precision § To demonstrate a sig change in group mean intakes, based on paired or unpaired be measurement Level 2 § To determine distribution of intake within group to assess proportion at risk of inadequate intakes § To determine a sig change in proportion at risk of inadequate intake between groups

METHODS AND OBJECTIVES (2/2) Level 3: Rank intakes of subject within the distribution § Multiple replicates of 24 -hour/diet records/diet history § Alternatively, SQ-FFQ Level 4: Usual Intakes for correlation or counseling or regression analysis § Larger number of replicate required § SQ-FFQ or diet history can be used Consider: respondent burden, available equipment, literacy, age, etc

EXAMPLE OF OBJECTIVE FOR LEVEL 3 AND 4 Level 3 § To asses the relationship between frequency of food group versus mean level of biomarker § To divide subjects into tertiles of nutrient intake and calculate the corresponding average biomarker level for each tertile Level 4 § To asses inter-relationship between nutrient intake of individual to other indices of nutritional status measured in the same person

FIGURE: THE FOUR LEVELS OF OBJECTIVES IN MEASURING NUTRIENT INTAKES AND METHODS WHICH CAN BE USED TO MEET THE OBJECTIVES LEVEL 1 Mean nutrient intake of a group All days of the week equally represented LEVEL 2 Proportion of population at risk At least 2 replicates in sub-sample Replicates in all SINGLE 24 hr-recall / food records / weighed diet records LEVEL 3 Usual intake of nutrients in individuals for ranking within a group MULTIPLE 24 hr-recall / food records / weighed diet records LEVEL 4 Usual intakes of foods / nutrients in individuals for counseling or for correlation or regression analysis Replicates in all Semi Quantitative-FFQ Diet History 13
