The predictors of glucose screening: the contribution of risk perception

Measurement of Perceived Risk of Developing Diabetes Mellitus: A Systematic Literature Review

BACKGROUND

This systematic review describes approaches to measuring perceived risk of developing type 2 diabetes among individuals without diagnoses and describes the use of theories, models, and frameworks in studies assessing perceived risk. While a systematic review has synthesized perceived risk of complications among individuals with diabetes, no reviews have systematically assessed how perceived risk is measured among those without a diagnosis.

METHODS

Medline, PubMed, PsycINFO, and CINAHAL databases were searched for studies conducted through October 2022 with measures of perceived risk among adults ≥ 18 years without a diabetes diagnosis. Extracted data included study characteristics, measures, and health behavior theories, models, or frameworks used.

RESULTS

Eighty-six studies met inclusion criteria. Six examined perceived risk scales' psychometric properties. Eighty measured perceived risk using (1) a single item; (2) a composite score from multiple items or subconstructs; and (3) multiple subconstructs but no composite score. Studies used items measuring "comparative risk," "absolute or lifetime risk," and "perceived risk" without defining how each differed. Sixty-four studies used cross-sectional designs. Twenty-eight studies mentioned use of health behavior theories in study design or selection of measures.

DISCUSSION

There was heterogeneity in how studies operationalized perceived risk; only one third of studies referenced a theory, model, or framework as guiding design or scale and item selection. Use of perceived lifetime risk, absolute risk, or comparative risk limits comparisons across studies. Consideration of context, target population, and how data are utilized is important when selecting measures; we present a series of questions to ask when selecting measures for use in research and clinical settings. This review is the first to categorize how perceived risk is measured in the diabetes prevention domain; most literature focuses on perceived risk among those with diabetes diagnoses. Limitations include exclusion of non-English and gray literature and single reviewer screening and data extraction.

Prenatal alcohol exposure risk perception dimensions and influencing factors: A systematic review and conceptual model

OBJECTIVE

This paper aims to explore the available literature to understand how risks regarding prenatal alcohol exposure are perceived.

METHODS

A systematic review (PROSPERO; CRD 42020212887) was undertaken. PubMed, Embase, PsycINFO, and CINAHL were searched for relevant quantitative and qualitative studies. A thematic analysis of the studies was performed.

RESULTS

Fifteen articles-nine quantitative and six qualitative studies met the inclusion criteria. Three dimensions of risk perceptions were identified-perceived susceptibility, perceived severity, and affective risk perception. Three influencing factors of these dimensions were also identified: information (i.e., consistency, confirmation bias, strength of the evidence, and perceived relevance), sociocultural (i.e., social inclusivity, cultural context, and risk interpretation), and individual (i.e., risks versus benefits, controllability, and experience). These dimensions and influencing factors were brought together to create the proposed novel Pregnancy Alcohol Risk Perception (PARP) conceptual model.

CONCLUSIONS

The novel PARP conceptual model developed from the current literature provides a framework to guide understanding of risk perceptions, which includes a wide range of potential influencing factors.

IMPLICATIONS FOR PUBLIC HEALTH

The novel PARP conceptual model provides the groundwork for further refinement with stakeholders, which could in turn be used to inform the design of interventions and health promotional materials to support harm reduction approaches and prevention of prenatal alcohol exposure.

Developing and validating a questionnaire to assess an individual's perceived risk of four major non-communicable diseases in Myanmar

Adopting healthy lifestyles is greatly influenced by an individual's perceived risk of developing non-communicable diseases (NCDs). This study aimed to develop and validate a questionnaire that can assess an individual's perceived risk of developing four major NCDs. We used the exploratory sequential mixed methods design. The qualitative part developed a questionnaire by two rounds of Delphi expert panels. The quantitative part validated the questionnaire using both exploratory (EFA) and confirmatory factor analysis (CFA). We used separate samples for EFA (n = 150) and CFA (n = 210). The participants were aged between 25-60 years of both sexes with no known history of NCDs, and face-to-face interviews were conducted. First, we generated an 86-item questionnaire based on the health belief model. Two expert panels ensured the questionnaire's content validity. The experts removed the overlapped items and items that did not represent the specific construct and developed a 51-item questionnaire. Next, we validated the questionnaire. We conducted a parallel analysis to determine the number of factors to be extracted. EFA constituted a five-factor model with 22 high loading items, which extracted 54% of the variance. We run four CFA models (single factor, five-factor, bifactor, and hierarchical) and tested the hypothesized five-factor model. It was found that the 21-item questionnaire (removed one efficacy item due to low loading) was satisfied with good psychometric properties and fitted with observed data in the bifactor model (RMSEA = 0.051, CFI = 0.954, TLI = 0.938, SRMR = 0.054). Hence, an individual's perceived risk of getting NCDs was constituted with a general perceived risk construct and five specific constructs (perceived susceptibility, perceived barrier, perceived benefit, perceived self-efficacy, and perceived behavioral change intention). It can be measured using the developed questionnaire (NCD-PR5-21). Further research is warranted to assess the questionnaire's utility in a mismatch between risk perception and current risk; and individualized counseling for behavioral change communication.

All things considered, my risk for diabetes is medium: A risk personalization process of familial risk for type 2 diabetes

BACKGROUND

A positive family history of type 2 diabetes (T2D) has been associated with risk awareness and risk-reducing behaviours among the unaffected relatives. Yet, little is known about how people with a positive family history for diabetes develop and manage their personal sense of risk.

OBJECTIVE

To characterize two key concepts, salience and vulnerability, within the familial risk perception (FRP) model among unaffected individuals, at increased familial risk for T2D.

DESIGN

We conducted a mixed method study. Descriptions of salience and vulnerability were collected through semi-structured interviews. Participant's perception of self-reported risk factors (family history, age, race/ethnicity, medical history, weight and exercise) was measured using the Perceived Risk Factors for T2D Tool and was compared to a clinical evaluation of the same risk factors.

RESULTS

We identified two components of salience: (a) concern for developing T2D and (b) risk awareness triggers, and two features of vulnerability: (a) statement of risk and (b) risk assessment devices. Although few participants (26%) were concordant between their perceived and clinical overall T2D risk, concordance for individual risk factors was higher, ranging from 42% (medical history) to 90% (family history).

DISCUSSION AND CONCLUSION

Both familial and non-familial events lead people to contemplate their T2D risk, even among people who have a positive family history. Participants often downplayed their overall risk and underestimated their overall risk compared to a clinical risk assessment of the same self-reported risk factors. Clinicians could leverage key components of the FRP process as way to engage patients in risk reduction strategies earlier.

Validation of a risk perception questionnaire developed for patients with rheumatoid arthritis

BACKGROUND

Risk perception is a multidimensional phenomenon that describes the individual's judgment of the likelihood of experiencing something unpleasant. Risk perception helps to understand how rheumatoid arthritis patients perceive disease-related-risks. We developed and validated a risk perception questionnaire for Spanish speaking rheumatoid arthritis patients.

METHODS

The questionnaire development and validation was performed in 3 steps, using respective convenience samples. Step-1 included the conceptual model construction, 20 patient's interviews to identify components from the conceptual model-dimensions and 11 healthcare provider´s consultations who identified RA related manifestations/complications (network and frequencies analysis). Step-2 consisted of item generation and reduction and questionnaire feasibility (n = 100). Step-3 consisted of the questionnaire psychometric validation (n = 270), which included content, face, construct (exploratory factor analysis) and criterion validity (logistic regression analysis) and consistency and stability (Cronbach's α and test-retest).

RESULTS

Samples were representative of typical RA outpatients. Initial conceptual model included 7 dimensions, 3 for probability and 1 each, for responsibility, prevention, control and for severity (Step-1). The final version was considered feasible by the patients and included 27 items (Step-2). A five-factor model was most appropriated and resulted in 68.8% of the variance explained: Cronbach's α = 0.90, intraclass-correlation-coefficient = 0.93 (95% CI = 0.90-0.95). A positive relation between number of external criteria from the charts and risk perception was found; all items had ≥80% agreement from experts; patients agreed about item´s semantic clarity (89%) and format adequacy (97%), (Step-3).

CONCLUSIONS

The risk perception questionnaire was valid and reliable to evaluate risk perception construct in RA outpatients; it can be incorporated to routine care and clinical research, and guide interventions to improve patient's health behaviors.

Accuracy of self-perceived risk for common conditions

Background:

Accurate awareness of common disease risk is necessary to promote healthy lifestyles and to prevent unnecessary anxiety and evaluation. Our objective is to identify characteristics of patients who do not accurately perceive their risk of developing coronary heart disease (CHD), diabetes (DM), breast cancer (BC) and colorectal cancer (CRC).

Methods:

Using personalized disease risk reports and risk perception surveys, subjects (n = 4703) were classified as high or low/average risk and high or low/average perceived risk for each condition. Models were used to examine factors associated with risk under-estimation by high risk patients and risk over-estimation by low/average risk patients.

Results:

Patients at high risk for DM, BC and CRC often (60%−75% of the time) under-estimated their risk, while low/average risk patients overestimated their risk 13%−40% of the time. For CHD, under-estimation by high risk individuals approximated over-estimation by low/average individuals. Compared to normal weight patients at high risk for cancer, obese patients were more likely to under-estimate their risk for BC (OR 3.1, CI 1.9–5.0) and CRC (2.6, 1.5–4.5) as were overweight patients. Overweight and obese patients at low/average risk of DM or CHD were more likely than normal weight patients to over-estimate their risk. Low/average risk women were more likely than men to over-estimate their risk of DM (1.3, 1.1–1.5) and CHD (1.8, 1.5–2.1).

Conclusions:

Our data show that body mass index is the factor most consistently associated with incorrect risk perceptions for several common conditions.

How to improve opportunistic screening by using EMRs and other data. The prevalence of undetected diabetes mellitus in target population in Croatia

OBJECTIVES

Opportunistic screening for type 2 diabetes (T2D) has not been adopted as part of routine practice. The aim of the study was to investigate the yield of opportunistic target screening for T2D in Croatia and to evaluate the process of screening by using data from electronic medical record.

STUDY DESIGN

We conducted opportunistic screening in 23 general practitioners (GPs) in a population of 13,344 patients aged 45-70 years.

METHODS

First, after excluding patients with T2D, patients with risk factors for T2D were derived from the electronic medical record and GP's assessment during the preconsultation phase. Second, those with data about normoglycemia in past three years were excluded. Remaining patients started the consultation phase during their usual visit, when they were offered capillary fasting plasma glucose testing in the next consultation.

RESULTS

Prevalence of T2D was 10.9% (new 1.4%). A total of 5568 (46.1%) patients had risks and 2849 (51.2%) had data about normoglycemia in the last three years. Using those data, number needed to invite to screening (NNI) was reduced to half: from 46.1% to 22.5%. One hundred eighty-four patients were screened positive for T2D in two capillary fasting plasma glucose tests (yield 9.8%). Number needed to screen (NNS) in order to detect one T2D was 10.3 patients. Among risks for T2D, overweight was the best predictive factor for undiagnosed T2D (odds ratio [OR]: 2.11, confidence interval [CI]:1.41-3.15, P < .001). Logistic regression showed that in targeted population, overweight patients with a family history in fold were 2.5 times more likely to have T2D (OR: 2.54, CI 1.78-.61, P < .001).

CONCLUSIONS

Total yield in targeted population was 1,4%. By using data about normoglycemia from EMRs, NNI was reduced by half and NNS was 10.3 patients. Our findings suggest the model for improvement in opportunistic screening.

Chronic Abdominal Pain in Children and Adolescents: Parental Threat Perception Plays a Major Role in Seeking Medical Consultations

Background. Pain symptoms, associated impairment, and parental perception of threat are reported to be predictors of health care utilization (HCU) in childhood chronic abdominal pain (CAP). However, mediating variables and their interrelations have not yet been systematically studied. Objectives. This study aims to identify mediating pathways of influence between child's abdominal pain and the number of pain-related medical visits. Methods. In a multicenter study, we recruited N = 151 parent-child dyads with children aged 6-17 years suffering from CAP. A composite measure of pain symptoms was defined as predictor and the number of pain-related medical visits as outcome variable. This relation was analyzed by serial mediation, including child- and parent-reported impairment and parental threat perception as mediators. Results. Only parental threat perception significantly linked child's pain symptoms to the number of medical visits. Measures of impairment did not have a significant effect. Conclusions. Parental pain-related threat perception is strongly related to health care seeking in childhood CAP. Addressing threat perception might be a fruitful parent-centered approach in clinical practice.

Risk perception in pregnancy: a concept analysis

AIM

To report an analysis of the concept of risk perception in pregnancy.

BACKGROUND

Pregnant women are increasingly exposed to the view that pregnancy and childbirth are intrinsically dangerous, requiring medical monitoring and management. Societal pressures are applied to women that dictate appropriate behaviours during pregnancy. These changes have resulted in increased perception of risk for pregnant women.

DESIGN

Walker and Avant's method was selected to guide this analysis.

DATA SOURCES

Peer-reviewed articles published in English from CINAHL, Scopus, PubMed and Psychinfo. No date limits were applied.

METHODS

Thematic analysis was conducted on 79 articles. Attributes, antecedents and consequences of the concept were identified.

RESULTS

The attributes of the concept are the possibility of harm to mother or infant and beliefs about the severity of the risk state. The physical condition of pregnancy combined with the cognitive ability to perceive a personal risk state is antecedents. Risk perception in pregnancy influences women's affective state and has an impact on decision-making about pregnancy and childbirth. There are limited empirical referents with which to measure the concept.

CONCLUSION

Women today know more about their developing infant than at any other time in history; however, this has not led to a sense of reassurance. Nurses and midwives have a critical role in assisting pregnant women, and their families make sense of the information they are exposed to. An understanding of the complexities of the concept of risk perception in pregnancy may assist in enabling nurses and midwives to reaffirm the normalcy of pregnancy.

Association Between Causal Beliefs and Shoe Wearing to Prevent Podoconiosis: A Baseline Study

Podoconiosis is a neglected tropical disease caused by long-term barefoot exposure to volcanic clay soil. Our previous qualitative research identified various domains of beliefs about the causes of podoconiosis held by members of the community. This cross-sectional survey, conducted in southern Ethiopia, aimed to quantitatively evaluate the prevalence of these beliefs and to assess their association with observed shoe-wearing behavior. A total of 1,800 adult respondents (600 from affected families and 1,200 from unaffected families of an index child aged between 3 and 6 years) took part in the survey. Two standardized versions of an enumerator-administered survey were created, with "all day, everyday" shoe-wearing status of the index child assessed in parallel for the affected and unaffected household respondents. Associations between measures were assessed using logistic regression. Accuracy of understanding about podoconiosis was significantly lower among respondents from unaffected than affected households (P < 0.001). Among affected respondents, beliefs about heredity were negatively associated with reported shoe wearing of the index child (odds ratio = 0.67, 95% confidence interval = 0.55-0.83). In both groups, associations of causal beliefs with shoe wearing were moderated by risk perceptions. Interventions aimed at preventing podoconiosis and improving shoe wearing should consider family-oriented education on hereditary susceptibility that targets affected and unaffected families in resource-limited settings.
