This may in part be owing to the complexity of psychosocial, biological, ethnic and environmental influences on health-related perceptions, treatment-seeking behaviour and decision making.<sup><xref rid="CIT0023" ref-type="bibr">23</xref>,<xref rid="CIT0029" ref-type="bibr">29</xref>,<xref rid="CIT0041" ref-type="bibr">41</xref></sup> The results of our research provide important insights into this research question.</p><p>The majority of our sample was women, despite the fact that men in the study area may also be likely to be at risk for obesity and NCDs. This finding is not uncommon in lifestyle intervention studies and it has been suggested that women seek treatment for obesity and general health problems more often than men do.<sup><xref rid="CIT0025" ref-type="bibr">25</xref>,<xref rid="CIT0042" ref-type="bibr">42</xref>,<xref rid="CIT0043" ref-type="bibr">43</xref></sup> This suggestion is supported by the findings of a recent study in North-West Province in South Africa, namely that men did not actively participate in healthcare-seeking behaviour and wellbeing when compared with women.<sup><xref rid="CIT0025" ref-type="bibr">25</xref></sup> Evidence from developed countries shows that men appear to prefer individualised treatment for health problems and a physical activity focus, over group-based weight loss programmes.<sup><xref rid="CIT0042" ref-type="bibr">42</xref>,<xref rid="CIT0044" ref-type="bibr">44</xref></sup> Our results indicate that the situation may be different in PHC settings in developing countries, with men being equally likely to choose group-based or usual care interventions as women. However, this trend would need to be confirmed by further research in PHC settings.</p><p>Although there were no differences in representation of races between treatment groups in our study, black participants were in the minority in both groups, which does not represent the demographics of the patients in the catchment area for the hospital. It has been reported that willingness to participate in weight loss interventions may be influenced by culture-related factors.<sup><xref rid="CIT0045" ref-type="bibr">45</xref>,<xref rid="CIT0046" ref-type="bibr">46</xref></sup> These studies showed that recruitment rates of black participants into health research and lifestyle programmes were generally low. A number of studies have shown that black South African women may perceive adiposity as a reflection of good health and wealth, while weight loss may be perceived as an indication of illness, especially regarding HIV or AIDS and poverty.<sup><xref rid="CIT0046" ref-type="bibr">46</xref>,<xref rid="CIT0047" ref-type="bibr">47</xref></sup> Therefore, cultural acceptance of a larger body size may thus contribute to low motivation to lose weight and thus low recruitment rates of black women into weight loss programmes. It can further be speculated that the perception among African-American women that weight loss and lifestyle programmes are not tailored to their personal challenges and cultural preferences<sup><xref rid="CIT0045" ref-type="bibr">45</xref>,<xref rid="CIT0048" ref-type="bibr">48</xref></sup> may also be true for black women attending the district PHC hospital in our study.</p><p>The mean of 10 years of education indicates that our sample (patients attending a PHC facility) on average have not completed secondary level education (12 years of schooling), with no difference between treatment choice groups. The low education level of the total sample may thus affect treatment outcomes and level of engagement in both treatment choice groups. Shankar et al.<sup><xref rid="CIT0049" ref-type="bibr">49</xref></sup> state that exposure to education over an individual’s life course is likely to affect the individual’s response to health problems in adult life. Low education attainment has been shown to be associated with reduced treatment-seeking behaviour,<sup><xref rid="CIT0050" ref-type="bibr">50</xref></sup> low desire to change, lower levels of health literacy,<sup><xref rid="CIT0048" ref-type="bibr">48</xref></sup> and poorer risk perception and external locus of control<sup><xref rid="CIT0051" ref-type="bibr">51</xref></sup> which could negatively affect treatment outcomes such as weight loss or adoption of a healthy eating pattern.</p><p>The total sample had an average household income of up to R4167.00 per month, with an annual income of up to R50 004.00, which is considerably less than the average annual income of R78 157.00 to R14 3460.00 in Western Cape Province, as reported in the 2011 Census.<sup><xref rid="CIT0052" ref-type="bibr">52</xref></sup> Although it has been suggested by the hospital administration that some patients under-report their income in order to qualify for lower hospital rates, the low income was expected as the catchment area for the hospital includes mainly low socio-economic households, education levels were low, and only half of the total sample were employed. It is plausible that low income may reduce treatment-seeking behaviour in general and, if treatment is sought, to opt for a less costly option. The perceived and actual higher cost of healthy eating<sup><xref rid="CIT0053" ref-type="bibr">53</xref></sup> may also be a barrier to enrolment in a lifestyle intervention for either treatment group. It is interesting to note that, despite the fact that there was no difference between treatment choice groups for employment status, usual care patients cited work commitments as the main reason for declining the FBTG intervention. It is plausible that unemployed or part-time employed individuals would be more likely to attend a regular FBTG programme or individual dietetic consultations (usual care choice) than employed individuals. However, financial constraints associated with unemployment may preclude them from doing so.</p><p>DM was more prevalent in our sample than CVD, with the elevated HbA1c in those with DM, especially patients in the usual care choice group, reflecting poor long-term blood glucose control. High BP and high cholesterol were present in the majority of the sample. Better control of blood glucose and hypertension was expected as pharmacological treatment for the management of these indicators seemed to be in place. However, only half of those with high cholesterol were on statins, possibly because doctors in this PHC hospital applied risk stratification in patient management that involves an initial focus on lifestyle change for patients who have high cholesterol levels, but are not at high risk for CVD. Factors such as poor compliance with treatment, age, weight status, unhealthy diet and physical inactivity might have contributed to the poor control of blood glucose, BP and cholesterol. Furthermore, NCD risk may be increased in the 16% current and 25% past smokers (= 41% ever smokers) in the total group. The Western Cape population is known to have the highest smoking prevalence in South Africa, with 38.5% being ever smokers, which is in line with our results but much lower than the national prevalence of 20.8%.<sup><xref rid="CIT0009" ref-type="bibr">9</xref></sup> Patients in the usual care choice group were significantly more likely to be current smokers, and may therefore be at higher risk for NCDs.</p><p>Although a BMI in the obese range was expected, it is very concerning that over a third (37.3%) of patients recruited into the study were morbidly obese (BMI > 40 kg/m<sup>2</sup>). Weight loss should clearly be a major priority in the treatment and management of these patients. The estimated mean 6-month weight loss goal of 12.7 kg for the total group (not significantly different between the two treatment choice groups) equates to approximately 0.5 kg per week and is in line with the general recommendation for weight loss of 0.5 kg to 1 kg per week.<sup><xref rid="CIT0054" ref-type="bibr">54</xref></sup> If this rate of weight loss is attained, a weight loss of 12.4% can be expected if the initial mean weight of 102.4 kg for the total group is considered. Modest but sustained weight loss of 10% of initial weight may result in substantial improvements in glycaemic control, BP and lipid profiles, if maintained.<sup><xref rid="CIT0055" ref-type="bibr">55</xref>,<xref rid="CIT0056" ref-type="bibr">56</xref></sup> Weight loss may also contribute to a reduction in waist circumference, which was in the undesirable range for almost all patients in the study sample, that will contribute to further NCD risk reduction and improved management for those with DM and/or CVD as central adiposity is known to exacerbate insulin resistance, dyslipidaemia and hyperglycaemia.<sup><xref rid="CIT0032" ref-type="bibr">32</xref></sup> As there were no differences in anthropometric measures between the treatment choice groups, it is possible that weight status did not influence treatment choice in our study sample.</p><p>The need for individualised treatment appears to be an important consideration for patients seeking treatment for obesity.<sup><xref rid="CIT0018" ref-type="bibr">18</xref></sup> This may explain why the preference for individual consultations was the second reason most cited by patients in the usual care choice group after work commitments for declining participation in the FBTG intervention. This finding is supported by Parker et al.<sup><xref rid="CIT0018" ref-type="bibr">18</xref></sup> who found that the majority of patients interviewed in PHC facilities in Western Cape Province opted for individual counselling as their ideal delivery method for therapeutic nutrition education. On the other hand, patients also seem to choose group-based weight loss programmes for professional guidance and peer support.<sup><xref rid="CIT0018" ref-type="bibr">18</xref>,<xref rid="CIT0020" ref-type="bibr">20</xref></sup> It must, however, be noted that frequent individual counselling for all patients with obesity or other risk factors for NCDs will remain a challenge for health professionals working in PHCs, as both medical<sup><xref rid="CIT0018" ref-type="bibr">18</xref></sup> and dietetic<sup><xref rid="CIT0057" ref-type="bibr">57</xref></sup> human resources are inadequate to meet the increasing burden of obesity and NCDs.</p><p>One of the most concerning findings among the total group of patients in the present study is the combination of the low level of self-reported physical activity and the time spent watching TV (2 hours per day on average), which was equally poor in both treatment choice groups. Time spent watching TV is often used to gauge the level of sedentary activity.<sup><xref rid="CIT0035" ref-type="bibr">35</xref></sup> Excessive TV viewing (2–4 hours per day) is considered an unhealthy behaviour as it is known to displace formal moderate physical activity and promote the consumption of unhealthy snacks and beverages, increasing the incidence and mortality from DM and CVD.<sup><xref rid="CIT0035" ref-type="bibr">35</xref></sup> The proportion of the sample who were physically inactive was 86%, which is much higher than the national prevalence of inactivity for men (44.7%) and women (47.6%).<sup><xref rid="CIT0058" ref-type="bibr">58</xref></sup> It is also higher than the prevalence of 66.5% found in a study of urban dwellers in Free State Province in South Africa.<sup><xref rid="CIT0006" ref-type="bibr">6</xref></sup> Furthermore, the reported 21 minutes per week of physical activity in the total sample is much lower than the 150 (for general health) to 300 minutes per week recommended by the WHO for adults aged 18 to 64 years old, to reduce the risk of NCDs.<sup><xref rid="CIT0034" ref-type="bibr">34</xref></sup> The causes of low physical activity were not assessed in this sample, although other research has indicated that socio-environmental factors such as poor neighbourhood safety, lack of recreational space, and lack of exposure to physical activity education over an individual’s lifetime are the primary causes.<sup><xref rid="CIT0059" ref-type="bibr">59</xref></sup></p><p>The present study demonstrated that the dietary intake reflects the ‘Western’ eating patterns that have been associated with an increased risk of developing NCDs.<sup><xref rid="CIT0010" ref-type="bibr">10</xref>,<xref rid="CIT0060" ref-type="bibr">60</xref></sup> On average, 8.4 standard portions of fats, high fat foods and energy-dense snacks (combined), 1.3 glasses of sugar-sweetened beverages and approximately five teaspoons of added sugar were typically consumed by our sample per day. Furthermore, refined carbohydrates (10.6 standard portions per day) were consumed more regularly than high-fibre foods (3.1 standard portions per day) and the usual care choice group had a higher intake of refined carbohydrates. The patients in the present study reside in urban communities where there is access to a variety of fast-food restaurants and informal vendors who typically sell foods that are energy-dense and high in fat, salt, sugar and refined carbohydrates. Alcohol intake amounted to approximately half a unit per day, which is in line with recommendations of one unit per day for women and two for men.<sup><xref rid="CIT0061" ref-type="bibr">61</xref></sup> Although moderate alcohol intake has been associated with decreased CVD risk and DM incidence, excessive alcohol intake may increase the risk for high BP.<sup><xref rid="CIT0062" ref-type="bibr">62</xref></sup> It is possible that some patients might have underreported their alcohol intake, which has been found to be a limitation in other South African studies investigating alcohol intake.<sup><xref rid="CIT0063" ref-type="bibr">63</xref></sup></p><p>Fruit and vegetable intake was low at 2.2 standard portions per day and falls short of the recommendations made by the 2012 South African food-based dietary guidelines that promote a minimum of five portions per day<sup><xref rid="CIT0036" ref-type="bibr">36</xref></sup> and also the recommendations of the dietary approaches to stop hypertension (DASH) programme that promotes 8 to 10 portions of fruit and vegetables per 8400 kcal.<sup><xref rid="CIT0064" ref-type="bibr">64</xref></sup> Low intakes of fruit and vegetables may increase the burden of disease and reduce survival rates.<sup><xref rid="CIT0036" ref-type="bibr">36</xref></sup> Low intakes in South African populations are not uncommon, with primary school educators in lower socio-economic areas in the Western Cape<sup><xref rid="CIT0029" ref-type="bibr">29</xref></sup> and South Africans in general<sup><xref rid="CIT0036" ref-type="bibr">36</xref></sup> reportedly consuming less than the FBDG recommendation. Intake of low-fat food choices, reflecting healthy lower fat choices over energy-dense, high fat or fried foods, was low at 2.4 standard portions per day. It is known that healthy food choices are affected by their cost, preference and access as well as cultural acceptance, knowledge and perceived control over healthy food choices.<sup><xref rid="CIT0053" ref-type="bibr">53</xref>,<xref rid="CIT0065" ref-type="bibr">65</xref></sup> It could therefore be argued that health education may not be sufficient to change purchasing and eating behaviours if the cost of healthy foods continues to be unfavourable, while cheap, unhealthy foods are readily accessible in urban communities. In line with findings from educators in low socio-economic areas in Cape Town,<sup><xref rid="CIT0029" ref-type="bibr">29</xref></sup> our results show that the patients’ meal patterns were regular, with infrequent snacking. The latter was more frequent in patients who chose the FBTG intervention, but still below two times per day.</p><p>Finally, over and above the presence of a high BMI (obesity), the top three risk factors for NCD development in the total group and in each treatment choice group were inadequate physical activity, low fruit and vegetable intake, and high blood pressure. It is important to note that, if the burden attributable (in percentage) to each of these three risk factors plus being obese in terms of death as reported by Norman et al.<sup><xref rid="CIT0066" ref-type="bibr">66</xref></sup> are summed, the total attributable burden of death from these four risk factors is 22.5%. Our findings are similar to those found in a cross-sectional study of urban dwellers in Free State Province in South Africa that ranked physical inactivity, high BMI, hypertension, smoking and high cholesterol in descending order as the primary risk factors for NCDs in their study sample.<sup><xref rid="CIT0007" ref-type="bibr">7</xref></sup> The mean number of risk factors was close to four in both groups, which was expected as the sample included patients seeking treatment for NCD-related conditions. The significantly higher number of risk factors in the usual care choice group is an interesting observation, especially as it seemed to be as a result of a higher prevalence of smoking and lower proportion of patients achieving five fruit and vegetable portions daily in the usual care group. Jimenez-Garcia et al.<sup><xref rid="CIT0067" ref-type="bibr">67</xref></sup> reported that patients who presented with several risk factors such as smoking, high alcohol intake, physical inactivity and poor diet were more likely to be non-adherent to lifestyle guidelines and have fewer contacts with health professionals. It could be argued that usual care patients were less likely to have changed their lifestyle in the past six months and therefore chose the less intensive usual care option. However, this possibility is not supported by the results of our stages of change assessment, as there were no significant differences between the two treatment choice groups for stages of change. It is important to note that the majority of patients in the total sample were in the contemplative stage, indicating that they were not actively changing unhealthy food choices yet may show intention to change behaviour.<sup><xref rid="CIT0068" ref-type="bibr">68</xref>,<xref rid="CIT0069" ref-type="bibr">69</xref></sup></p><p>The findings of the present research need to be considered while bearing in mind the limitations of using self-reported data. The comprehensive process followed in the development of the questionnaire, as well as the fact that all interviews were conducted by the same well-trained dietitian addresses some of these concerns. Although content, construct and face validity of the food list included in the FFQ were ensured, validation of the daily frequency of intake of items in the indicator food groups is recommended. A further limitation is the fact that data for biochemical measures, including HbA1c and cholesterol levels, were not complete, reducing the sample size and therefore power to detect differences between treatment choice groups for these variables.</p></sec><sec id="s0024"><title>Conclusion</title><p>The primary aim of the present research was to describe the characteristics of patients seeking treatment for NCDs and/or risk factors for NCDs. The socio-demographic and health profile of this urbanised sample of obese patients with NCDs (DM or CVD) or risk factors for NCDs shows that treatment-seeking patients attending a district PHC hospital in Cape Town were representative of a middle-aged, low income group comprising mostly coloured women. The most prevalent NCD among this sample was DM, followed by CVD, while the majority of patients suffered from hypertension and over two-thirds had high cholesterol despite the availability of pharmacological treatment. The sample was also characterised by low levels of physical activity and poor food choices that may explain the seemingly poor management of the diseases, as well as the intermediate risk indicators, including obesity. Patients choosing the less intensive usual care may have more NCD risks as they had a higher smoking prevalence, HbA1c, number of NCD risk factors and refined carbohydrate intake, and a lower proportion consumed adequate fruit and vegetables.</p><p>The baseline patient profile may aid intervention planners, including the DoH, to ensure the planning of appropriate lifestyle interventions. The results clearly point to the importance of including a strong focus on healthy eating and physical activity options in interventions targeted at patients with NCDs or risk factors for NCDs. The inclusion of specific lifestyle advice for the management of hypertension, hypercholesterolaemia and hyperglycaemia is deemed necessary. It is also important that a behaviour change theory or model should be used in planning and implementing such lifestyle interventions. We recommend that future qualitative research should also investigate the reasons for choosing or declining specific weight loss interventions.</p></sec></body><back><ack><title>Acknowledgements</title><p>We extend sincere gratitude to Henri Carrara from the University of Cape Town for assisting with general statistical support, and all the staff at False Bay Hospital who provided exceptional encouragement and support for this research.</p><sec id="s20025"><title>Competing interests</title><p>The authors declare that they have no financial or personal relationships that may have inappropriately influenced them in writing this article.</p></sec><sec id="s20026"><title>Authors’ contributions</title><p>K.M. conducted the research under supervision of J.H. and co-supervision of M.S.
