Cross sectional/Longitudinal

Generic WHOQOL - bref

First time

30 (57% male)

Range: 60–90 years, mean age 76.8 years

bilateral

Moderate hearing loss. No further definition.

Before HA fitting (ISAD) and after 3 months.

Using HA (ISAD) improved the overall QoL

25

Chew, H. S. and S. Yeak, 2010 [49]

Cross sectional

Generic: SF 36

First time

80 (41% male)

Range: 50 years and over. Median age 69 years

bilateral

>25 dB PTA in the better ear.

Not specified

SF-36 lacked specificity and sensitivity in assesing the impact on HL on QoL

21

Chia, E.-M., et al., 2007 [50]

Cross sectional

Generic: SF 36

Not specified

2431

Mean age: 67 years

Unilateral and bilateral

Unilateral HI defined as HI in one ear and no HI in the other ear. Bilateral HI defined as HI in both ears. HI defined as >25 dB PTA

Not specified

Unilateral HL: No significant difference in QoLthan those whitout HL. Bilateral HL: Poorer QoL than those whitout HL.

Dalton, D. S., et al., 2003 [44]

5- year follow-up Longitudinal

SF-36 (Generic)

Not specified

2688, (42% male)

53–97 years, mean age 69 years

Not specified

Mild: 26–440 dB PTA HL in eighterear. Moderate to severe: >40 dB PTA in eighter ear

Not specified

HL was associated with reduced QoL.

36

Espmark, A. K. K., et al., 2002 [47]

Cross sectional

HMS (26 questions, where 4 of 20 items where related to QoL)

First time

154 (38% male)

Born 1920 or earlier

Not specified

Three groups: Normal to slight HL: <30 dB PTA. Mild HL: 30–39 dB PTA. Moderate to severe HL: ≥ 40 dB PTA

Hallberg, L. R., et al., 2008 [51]

Cross sectional

PGWB

Mixed

79 (39% male)

48–92 years, mean age 68.7 years

Bilateral

PTA low at Freq.0.5, 1 and 2 kHz was 39.6 dB. PTA high at Freq. 2,3,4 and 6 kHz was 55.5 dB

Not specified

HL was significantly associated with reduced QoL. Psychsocial consequenses of HI, such as lowered QoL, cannotbe predicted from audiometric data alone.
