One is the cross-sectional study design, which does not allow for the prediction of a causal relationship between the variables. Future research should use longitudinal data to examine the relationship between feelings of loneliness, malnutrition, and subjective age. A further limitation is the use of only one question concerning loneliness. However, previous studies have also used a single question for this purpose [77]. Third, the ability to generalize the findings is limited, because the sample and the sampling procedure did not guarantee the representativeness of Jewish and Arab older adults. The sample included only older adults who answered the telephone at the moment the researchers called. Those who did not answer or did not have a telephone are not represented in this study. Fourth, all variables were measured at the same time, therefore, general attitudes and emotions may have had an influence on all ratings. These various factors may have biased the results."}
